In this application, the base junction is forward biased. With Schottky diodes, the turn-off time is significantly reduced and the speed of the circuit is increased. Why Schottky diodes are fast?The small amount of charge stored within a Schottky diode makes it ideal for high speed switching applications. Less noise. The Schottky diode will produce less unwanted noise than your typical p-n junction diode. What metal is used in Schottky diode?A metal-semiconductor junction is formed between a metal and a semiconductor, creating a Schottky barrier instead of a semiconductor-semiconductor junction as in conventional diodes. The semiconductor would typically be N-type silicon and typical metals used are molybdenum, platinum, chromium or tungsten. Why Schottky diode is unipolar?The schottky barrier diode has electrons as majority carriers on both sides of the junction. So it is a unipolar device. Thus there is no depletion layer formed near the junction. It give very less voltage drop across the junction. What is difference between Schottky diode and normal diode?Schottky generally has lower reverse voltage max. You can easily find silicon diodes with 20-1400v ranges, while commonly schottky is 20v-60v. Schottky is extremely fast recovery, even faster than so-called “fast recovery” silicon diodes. What type of diode is the 1N5711? Schottky diode

I DescriptionClass D power amplifiers are often used for music playback of various electronic products in daily life. The Class D power amplifier in this blog uses the NE5532 operational amplifier and LM311 to form a self-oscillation to generate a 150kHz carrier wave and modulate the input low-frequency signal into a constant-amplitude pulse. Then the power amplifier pushes the moving tube. Finally, the low-frequency signal is separated by filtering.Figure 1. Class-D Power AmplifierCatalogI DescriptionII How to Choose an AmplifierIII Working Principle of Class D AmplifierIV Principle Block DiagramV Working Principle5.1 Channel Selection and Display Principle5.2 Carrier Generation Circuit5.3 Comparator Circuit5.4 Drive Circuit and Power Amplifier Circuit5.5 Low-pass FilterVI ConclusionFAQOrdering & QuantityII How to Choose an AmplifierTraditional power amplifiers  mainly fall into the following three categories:Class A power amplifiers.  ;Class AB power amplifiers  ;Class B power amplifiers,  Class A power amplifiers mainly amplify small signals and need to set a bias voltage to stabilize the circuit, so the efficiency is low.Class B power amplifiers do not rely on bias voltage for amplification but use the principle that when the input signal is greater than the conduction voltage of the transistor, the transistor is turned on for amplification. Since the input signal is divided into positive and negative, it needs to use 2 triodes for amplification. Because when the input signal is less than the turn-on voltage, that is, in the range of -0.6V to 0.6V, the transistor cannot be turned on. Therefore, the input signal cannot be amplified and there is distortion. Therefore, a Class AB power amplifier is proposed.Class AB power amplifier, because it directly amplifies the analog signal when it works, it requires the transistor to be in a linear amplification state. Therefore, too much power consumption needs to be dissipated, which also has drawbacks.Class D power amplifier overcomes the drawbacks of the above class A power amplifier, class AB power amplifier, and class B power amplifier. It uses pulse high and low-level control switching devices to turn on and off. Then the voltage and current of the output signal have been amplified, that is, the power is amplified, so the power consumption is very small.III Working Principle of Class D AmplifierFirst, use the op amp self-oscillation to generate a high-frequency carrier, and then modulate the input low-frequency analog signal to a high-frequency signal through a comparator. This modulating wave is a series of pulse signals of constant amplitude whose width is modulated and the frequency changes with the amplitude of the low-frequency signal. This process is also called pulse width modulation, or pulse width modulation for short.This system is generally composed of a comparator, the input signal is a triangle wave (carrier) and a low-frequency signal, and the two signals are compared. If the low-frequency signal is greater than the triangle wave signal, the comparator outputs a constant. If it is less than, 0 is output. Therefore, the comparator output is a series of modulated pulse width modulated waves. The output modulation wave is amplified by the switching power and filtered to output a low-frequency signal.IV Principle Block DiagramFigure 2. Principle Block DiagramV Working Principle5.1 Channel Selection and Display PrincipleChannels can be divided into 1 channel and 2 channels. The selection circuit uses the 74ls74 chip, which is a dual-rising-edge D flip-flop chip with a total of 14 pins. Since the input signal is a low-frequency analog audio signal, the multiplexer of this blog uses a 74HC4052 chip.When the output terminal of the D flip-flop is high, the digital tube displays 2. At the same time, the signal enters the 10th pin of 74HC4052. The chip's digital selection terminal selects Y1 channel signal input and output Y1 signal, that is, channel 2 is selected.When the output of the D flip-flop is low, the digital tube displays 1. At the same time, the signal enters the 10th pin of 74HC4052. The digital selection terminal of the chip selects Y0 channel signal input and output Y0 signal, that is, channel 1 is selected.5.2 Carrier Generation CircuitThe carrier wave used in this blog is a triangular wave with a frequency of 170kHz.The function of the carrier is to modulate the input analog low-frequency signal to high-frequency to form a modulated wave.The circuit uses NE5532 operational amplifier and voltage comparator LM311 to form a self-oscillation.When setting the circuit parameters, it should be noted that the chips are all powered by a 5V power supply, and the operational amplifier can be divided by a 10kΩ resistor to make the voltage divided into 2.5V. At the same time, it is required to set the parameters so that the amplitude of the carrier output is 3V.5.3 Comparator CircuitThe circuit in this article uses an LM311 chip. The power supply voltage of the chip is 5V. In order to obtain a static potential of V+=V-=2.5V, the resistance value of the 4 resistors is 10kΩ.Since the carrier Vp-p=3V, Vp-p of the audio signal is required to be 4V or less. Otherwise, it will cause distortion. This part is used as a modulator circuit, and the original input audio signal is input to the 2-pin positive input terminal of the operational amplifier LM311 after channel selection, amplification, and  DC  bias. Generate a triangular carrier wave through the self-oscillation circuit and input it to the 3-pin negative input terminal of the comparator LM311.When the voltage on the positive terminal of pin 2 is greater than the voltage on the negative terminal of pin 3, the output will be high, otherwise, it will be low. When there is no input signal, the voltage value of the  DC bias is half of the peak value of the triangular wave. At this time, the output of the comparator is a square wave.When there is an audio signal input  and it is a positive half cycle, the comparator output high level time is longer than the low level time, and the duty cycle of the square wave is greater than one-half;In the negative half cycle, the voltage at the positive input of the comparator is greater than zero. However, the time for the audio signal amplitude to be higher than the triangular wave amplitude is greatly reduced, and the square wave duty cycle is less than one-half. Therefore, the waveform output by the comparator is a waveform whose pulse width is amplitude modulated by the audio signal.In this way, low-frequency audio information is modulated into the pulse waveform. The waveform is shown in Figure 3.Figure 3. Modulation Waveform Graph5.4 Drive Circuit and Power Amplifier CircuitThe drive circuit adopts IR2110 full-bridge drive. The power amplifier circuit uses a class D power amplifier, which is a pulse-controlled high-current switching amplifier. It turns the  PWM  signal output by the comparator into a high-voltage, high-current, high-power  PWM signal.5.5 Low-pass FilterThe 150kHz carrier uses a fourth-order LC filter. The function is to separate the low frequency signal from the PWM waveform.Working principle: When a pulse with a duty cycle greater than one-half arrives, the charging time of the capacitor is longer than the discharging time, and the output level rises. When the narrow pulse arrives, the discharge time of the capacitor is longer than the charging time, and the output level decreases, which coincides with the amplitude change of the original audio signal. So that the original audio signal is separated.VI ConclusionUse NE5532 and LM311 operational amplifiers to design class D  power amplifiers,  By making PCB boards, soldering, debugging, and realizing corresponding functions, the sound quality is better. So it is a more practical class D power amplifier. The circuit design and production are suitable for students who have a good grasp of analog and digital electronics and have a certain design foundation. This experiment will enable them to master electronic technology.FAQWhat is NE5532？The NE5532 is a Dual Low Noise Op-Amp in 8-pin package commonly used as amplifiers in audio circuits for its noise immunity and high output drive capability. The Op-Amp is internally compensated for high unity gain with maximum output swing bandwidth, low distortion and high slew rate.How to check NE5532 IC with digital multimeter?Whats the size of NE5532 produced by Texas Instruments? Anything to compare?You will find all physical sizes in inches as well as millimeters in page 19 of the official TI datasheet at:http://www.ti.com/lit/ds/symlink/ne5532.pdfHow to use LM311?LM311 is a single-channel comparator. When using it, connect the reference voltage and the compared signal voltage to its non-inverting and inverting input terminals (pin 2 and pin 3), and its output is the result of the comparison. If you want the foward output result, pin 7 is connected to the positive power supply and pin 1 is the output. If the result is to be output in reverse, pin 1 is grounded and pin 7 is the open collector output.lm311 and lm393 are both voltage comparators, so what is the difference between them?LM311 is single voltage comparaotor, LM393 is dual voltage copatpr. LM311 has a load current of up to 50MA and a voltage of 40V. It can drive relays with a minimum power supply voltage of 5V.The LM393 load current is 16MA, and the minimum voltage is 2V for a single power supply.What’s the difference between LM311 and LM111?Their functions are the same, and the 1XX series can be used in harsher environments.The 3XX series can only be used in a commercial environment, typically the applicable temperature range of the device.The price of 1xx is much more expensive than 3xx.What does the 5 and 6-pin balance strobes of LM311 mean?The function of balancing the mirror current of the reverse circuit is realized by connecting a potentiometer in the middle. In addition to the balance function, the 6 pin also has a strobe function, and the 6 pin can be grounded through the transistor drive circuit for strobe output.What is the difference between lm311 voltage comparator dual power supply and single power supply?The comparators are all open-collector outputs, without load resistance, they cannot output voltage signals.Dual power supplies can detect signals lower than 0, and single power supplies can only detect signals higher than 0.Can the lm311 comparator be powered by a positive and negative five-volt dual power supply?Of course, LM311 can be powered by ±5V dual power supply. Its requirement for working power supply is that the voltage difference between the positive and negative power supply (or single power supply voltage) is at least 3.5V and the maximum is 30V, as long as it is within this range. 

The LM2940 is a common low-dropout (LDO) linear regulator.  This is a comprehensive introduction to the LM2940 voltage regulator, from its pinout, feature, parameter to its application, its difference between LM7805, and more.CatalogLM2940 DescriptionLM2940 PinoutLM2940 FeaturesLM2940 ParametersLM2940 EquivalentLM2940 VS LM7805LM2940 Typical ApplicationLM2940 PackageLM2940 ApplicationComponent DatasheetFAQLM2940 DescriptionThe LM2940  is a common low-dropout (LDO) linear regulator,   The dropout voltage of a regulator is the voltage required between the input and the regulated output voltage. The regulator wastes this voltage (multiplied by current), so the lower the dropout on a linear regulator.  the more efficient it is. This means that the LM2940.  with a 5V dropout at 1 amp, can be used with a 6-volt wall wart to provide a regulated 5V output. This also means that the regulator will operate at a much lower temperature than a standard 7805, which would require a much higher input voltage (around 7.5 volts) for a regulated 5V output.LM2940 PinoutLM2940 voltage regulatorLM2940 Pinout Pin No.Pin NameDescription1VinA (+ve) voltage is given as input to this pin.2GNDCommon to both Input and Output.3VoutOutput regulated 12V is taken at this pin of the IC.LM2940 FeaturesInput Voltage Range = 6 V to 26 VDropout Voltage Typically 0.5 V at IOUT = 1 AOutput Current in Excess of 1 AOutput Voltage Trimmed Before AssemblyReverse Battery ProtectionInternal Short Circuit Current LimitMirror Image Insertion ProtectionP+ Product Enhancement TestedLM2940 ParametersOutput optionsFixed OutputIout (Max) (A)1Vin (Max) (V)26Vin (Min) (V)6Vout (Max) (V)15Vout (Min) (V)5Fixed output options (V)5, 8, 9, 10, 12, 15Noise (uVrms)150Iq (Typ) (mA)10Thermal resistance θJA (°C/W)23Load capacitance (Min) (µF)22RatingCatalogRegulated outputs (#)1Features-Accuracy (%)2PSRR @ 100 KHz (dB)48Dropout voltage (Vdo) (Typ) (mV)500Operating temperature range (C)-40 to 125, -40 to 85LM2940 Equivalent The equivalent for LM2940 is LM7805.LM2940 VS LM7805 The LM7805  is a popular linear voltage regulator because it requires no additional components to operate. It is a very low-cost component. Because of its characteristics, it reduces the output voltage at the expense of heat dissipation, making it inefficient. The LM7805  requires a minimum input voltage of 7.3V to function properly. It can handle a maximum current of 1A. Some models can handle up to 1.5A. It is recommended, and in some cases required, to use capacitors to reduce or eliminate the effects of the frequencies introduced by the other elements of the circuit. They also help to reduce the impact of peak consumption. While the LM2940  is from a different generation, but its pin is still compatible with the LM7805,   It is a Low-dropout (LDO) Linear Regulator that is more efficient than the LM7805.  but it will require capacitors. The main difference between LM2940  and LM7805  is that the maximum output current of LM2940  is 1A. The maximum output current of LM7805  is 1.5A. Others are very close, so if the circuit only requires 1A or below, LM2940  can be used instead of LM7805,   What's more, the 7805 is expending the excess power as heat. This is very lossy especialy if your project uses batteries. The other chip is a buck converter  is so it approaches 90% efficiency by switching so there is no waste heat, that's why even though LM7805  is cheaper and easier to use but there are still a lot of people who would go for LM2940. LM2940 & LM7805 Schematic ComparisonLM2940 SchematicLM7805 SchematicLM2940 Typical ApplicationLM2940 PackageLM2940 ApplicationPost regulator for switching suppliesLogic power SuppliesIndustrial InstrumentationComponent Datasheet LM2940 DatasheetFAQWhat type of linear regulator is the LM2940?Low-dropout What can the LM2940 be used with to provide a regulated 5V output?A 6 volt wall wart What is the minimum input voltage for the LM7805?7.3V What is the maximum current of the LM7805?1A What is the purpose of the LM7805?To reduce or eliminate the effects of the frequencies introduced by the other elements of the circuit What does the LM7805 help to do?Reduce the impact of peak consumption What is the LM2940?Low-dropout (LDO) Linear Regulator What is the difference between LM2940 and LM7805?The maximum output current of LM2940 is 1A.

The unit combines high linearity and high accuracy sensors and is perfectly feasible for low current consumption, long-term stability and high EMC robustness.How does bme280 work?The BME280 sensor module reads barometric pressure, temperature, and humidity. Because pressure changes with altitude, you can also estimate altitude. There are several versions of this sensor module. The BME280 sensor uses I2C or SPI communication protocol to exchange data with a microcontroller.How do I connect my raspberry Pi to bme280?Wiring1.Connect the Raspberry Pi 3.3V power pin to Vin.2.Connect the Raspberry Pi GND pin to GND.3.Connect the Pi SDA pin to the BME280 SDI.4.Connect the Pi SCL pin to to the BME280 SCKHow to interface a bme280 with arduino?Wiring BME280 Module to Arduino UNOConnections are fairly simple. Start by connecting VIN pin to the 5V output on the Arduino and connect GND to ground. Now we are remaining with the pins that are used for I2C communication. Note that each Arduino Board has different I2C pins which should be connected accordingly.What are i2c sensors?The I2C bus is a simple and flexible way to transfer digital data between two electronic devices which may be physically seperate or contained on the same printed circuit board (PCB).How do I use i2c with a bme280 sensor?The BME280 supports either SPI or I2C interface to communicate with the micro controller. Because of the small size of the sensor, the best way to use this sensor is with a breakout board. The Adafruit breakout board is used here. In this hookup we are only connecting one device to the Arduino using the I2C bus. We can use either address (0x77 or 0x76). It reads the barometric pressure, humidity and temperature and displays it on the console.
