IntroductionLM3886 is a high-performance audio power amplifier. It exhibits extremely low THD+N values of 0.03% at the rated output into the rated load over the audio spectrum and provides excellent linearity with an IMD (SMPTE) typical rating of 0.004%. It is very suitable for enthusiasts who pursue both beautiful sound quality and strong volume. This article introduces several practical applications of LM3886 in home theater systems.This is a technical examination vedio of the LM3886 Amplifier. Catalog IntroductionCatalogI High Quality Dual-channel Power AmplifierII Powerful BTL Power AmplifierIII Subwoofer SpeakerIV FAQOrdering & QuantityI High Quality Dual Channel Power AmplifierLM3886 outputs nearly 70W power at rated voltage and the peak power is 150W. The dual-channel power amplifier adopts a simple and typical circuit, which can replace a variety of HI-FI power amplifiers,  and is suitable for the left and right main channel of a power amplifier in home cinema. The whole circuit is installed on the same PCB. Each of the two LM3886s is equipped with a special aluminum radiator (length 140, thickness 50, height 75 (mm)), which are fixed on both sides of the PCB to facilitate heat dissipation. The power transformer can choose double 24～28V, 3～5A.II Powerful BTL Power AmplifierA pure BTL bridge amplifier is composed of an operational amplifier NE5532, an LM3886 in-phase amplifier, and an LM3886 inverting amplifier, which can easily output more than 200W undistorted power. It can be used in dance halls, karaoke, theaters, and other occasions. This circuit can keep the sound quality natural and smooth when playing at a low volume. BTL Power amplifier circuit is shown in Figure 1. One circuit board for each channel, with independent rectification. The size of the two radiators is 140mm in length, 50mm in thickness, and 100mm in height.　　Figure 1. BTL Power Amplifier CircuitIII Subwoofer SpeakerFigure 2 is the circuit of a household subwoofer speaker.　　Figure 2. circuit of subwoofer speakerIn the picture, the Linkwitz active compensator accurately controls the center frequency f1 of the compensation peak and its Q value, so that the closed box (see Figure 3) with a natural corner frequency of about 50 Hz and the frequency response curve (see Figure 4) extends down flatly. The low end -3dB point reaches 25Hz.Figure 3. Closed box　　Figure 4. frequency response curveIn Figure 4, curve A is natural frequency response; B is compensation curve; and C is system frequency response. The turning frequency of the low-pass filter is continuously adjustable from 80Hz to 200Hz, so that the active subwoofer can match the reader's dual channel speaker with different frequency limits. The loudspeaker uses silver flute YD310-43. The basin diameter is 310mm. The magnet diameter is 158mm. The resonance frequency is 25Hz. Q=0.35. The continuous power is 50W, and the sensitivity is as high as 95dB. Compared with the Hivi S8 unit with a sensitivity of 88dB, the sensitivity difference between the two is 7dB. For the closed box, the output sound pressure of Yindi YD310-43 when it input 50W is equivalent to the output of Hivi S8 unit when it input ≥200W.  Yindi can also be replaced by the Blue Whale YD310-8XA. Instead of the bass reflex with poor transient performance and low sensitivity, it is better to use the simplest closed box. The box shall be solid and air tight, filled with glass fiber cotton or acrylic cotton for warmth absorption, and the small cavity at the bottom of the box shall be used to install the circuit part. For the sake of simple installation, all circuits are installed on the PCB. The PCB, radiator, switch and I/O connector are fixed on the metal panel, and then fixed on the speaker with 6 screws. Then, it can work after connecting to horn and transformer. Connect the subwoofer active speaker with the home stereo speaker to form a 3D playback system.IV FAQWhat type of amplifier is LM3886?High-performance audio power amplifier What is the THD+N value of LM3886?0.03% What type of systems is LM3886 used for?Home theater systems What is the peak power of the LM3886?150W How much power does the LM3886 output at rated voltage?70W How much undistorted power can a BTL bridge amplifier output?200W

There are three terminals: Vin, Vout, and Adj. This type of regulator is used to provide an additional 3 amps of current across an output range. This IC is extremely simple to use and only requires two external resistors to set the output voltage. In advance, it employs internal current limiting, safe area compensation, thermal shutdown, and so on. This regulator is used in many applications, including local and on-card regulation. We can use this regulator to design a programmable o/p regulator, an adjustable switching regulator, or a precision current regulator by using a fixed resistor between the two pins like adjustment & output.LM350 PinoutLM350 voltage regulatorLM350 voltage regulator pinout Pin NumberPin NameDescription1AdjustThis pins adjusts the output voltage2Output Voltage (Vout)The regulated output voltage set by the adjust pin can be obtained from this pin3Input Voltage (Vin)The input voltage which has to be regulated is given to this pinLM350 FeaturesDelivers an output current of 3 Amps.Output voltage is adjustable from 1.25V to 33V with 1% tolerance.Provides a load regulation of 0.1% and a line regulation of 0.005%/V.The chip can bear maximum input to an output voltage difference of 35V.

A three-terminal integrated circuit is what it is. This regulator can be found in a variety of applications. It can also function as a variable voltage regulator.LM350 Circuit DiagramWe've already mentioned this IC has three pins, one of which is connected to the Vin pin, which receives the input voltage. A potential divider is then used to fix a voltage at the adjusted pin. A voltage divider can be formed using a pair of resistors in this case. As a result, the output voltage can be determined using the Vout pin. The circuit's pair of resistors can be connected to Vout. A potentiometer is used to fix variable voltages at pin-1 within the potential divider to make this IC look like a variable voltage regulator. The potential difference can be created by connecting resistor R1 and the potentiometer at the adjusting pin, which controls the Vout pin according to the formula: VOUT = 1.25 × (1 + (R2/R1)) + Iadj(R2)Where to use LM350This regulator would be the first choice for variable voltage regulation requirements. Because this IC can supply up to 3A, we can use the LM350  IC if we need to supply more than 1.5A. A variable voltage regulator is used to fix the voltage between 1.25V and 33V and to supply current up to 3A.  This regulator is an excellent choice for a variety of applications. This regulator also includes a current regulator, which is used in battery charging applications.How to use LM350The majority of voltage regulators employ an input and output capacitor. The operation of the  LM350  is similar to that of other voltage regulators. You can adjust the values of the resistors connected between the adjustable and output pins to change the output voltage from 1.25V to 33V. The output capacitor enhances regulation as well as transient response. This device provides excellent load regulation. To achieve good regulation, the resistor R1 should be directly connected to the output to maximize performance.LM350 PackageLM350 ApplicationBattery chargersCurrent Limited chargersSwitching RegulatorsTemperature ControllersLight ControllerTracking Pre-regulatorLM350 ManufacturerTexas Instruments Incorporated (TI) is a global semiconductor design and manufacturing company that develops analog ICs and embedded processors.

The device has an open collector transistor output, so an external resistor is required to reach the appropriate logic levels. When the input signal is in the detection band, the device output changes to the LOW state.The internal free operating frequency of the VCO defines the center frequency of the detection band. An external RC filter is required to adjust this frequency. The bandwidth in which the device will detect the desired frequency depends on the capacity of the loop filter terminal. Usually, a 1µF capacitor is connected to this pin.LM567 is generally used in the following situations:Touch Tone DecodingPrecision OscillatorFrequency Monitoring and ControlWide Band FSK DemodulationUltrasonic ControlsCarrier Current Remote ControlsCommunications Paging Decoders Functional Block DiagramCircuit DiagramThe following describes the classic circuit diagram of the phase-locked loop LM567 used in carrier communication applications.
