I DescriptionThis blog will introduce a sound amplifier designed based on NE5532 and TDA2030 integrated circuits. It mainly includes the following parts: the composition, function and working principle of audio amplifier. In terms of its characteristics, this amplifier has the following advantages:Small transient intermodulation distortion;High output power;The circuit is simple & easy to make.This is why NE5532 can always be widely used in audio systems such as home audio and high-fidelity stereo.CatalogI DescriptionII Composition of Audio AmplifierIII Characteristics and Requirements of Circuits3.1 Pre-amplification Circuit3.2 Tone Control Circuit3.3 Power Amplifier CircuitIV Introduction of Integrated Devices4.1 Integrated Op Amp NE55324.2 Integrated Power Amplifier TDA2030V Design of Audio Amplifier5.1 Design of Preamplifier Circuit5.2 Design of Tone Control Circuit5.3 Design of Power Amplifier CircuitVI Sound Amplifier SimulationFAQOrdering & QuantityII Composition of Audio AmplifierIn your impression, what is an audio amplifier? An audio amplifier is a device that restores electrical signals to sound signals. It requires high output power, low distortion, and high efficiency.For integrated circuits, it has the characteristics of low price, light weight, and good performance, so it is widely used in audio amplifiers. This blog will conduct in-depth research on audio amplifiers, using NE5532 integrated operational amplifier and TDA2030 integrated power amplifier to design an audio amplifier.The audio amplifier circuit is mainly composed of 3 parts:Preamplifier circuit;Tone control circuit;Power amplifier circuit.The microphone signal is first amplified by the amplifier. Then, the signal enters the tone control circuit for high and low tone control. Finally, it enters the power amplifier for amplification to provide the maximum undistorted audio power to the speaker. Users can boost or attenuate the bass with 100Hz as the control point and the treble with 10kHz as the treble control point according to their needs. In the end, satisfactory treble and bass control effects can be obtained. Its circuit composition block diagram is shown as in Fig. 1.Figure 1. Block Diagram of Sound Amplifier CircuitIII Characteristics and Requirements of Circuits3.1 Pre-amplification CircuitThe pre-amplifier amplifies the audio signal so that the amplified signal is within the input range of the power amplifier. The input sound of the audio amplifier is very different, and the output voltage range is also very large. Some input signals need to be power compensated first and then amplified by a power amplifier, which can make the frequency characteristic curve more flat.Therefore, the main functions of the preamplifier are as follows:Matching impedance;The matching of voltage amplitude and sensitivity.There are also the following two requirements for preamplifiers:The noise of the power tube should be very low; Ensure that its frequency band is wide enough.Only by meeting these two requirements, can the signal of the preamplifier be output without distortion.3.2 Tone Control CircuitThe main function of the tone control circuit is to adjust the frequency response curve shape of the audio amplifier in the audio frequency band. In other words, by boosting a certain frequency band signal or attenuating a certain frequency band signal. The signals in other frequency bands remain unchanged.Tone Control Circuit is mainly composed of a high-pass filter and a low-pass filter. Therefore, on the one hand, it can control the timbre of the audio signal; on the other hand, it also can compensate for the lack of frequency components in the signal. In this way, not only the tone of the sound reproduction system is improved, but also the sound reproduction effect of the sound is improved.In the high-fidelity stereo audio playback circuit, we usually use a tone control circuit with adjustable treble and bass. If the performance of a tone control circuit is good enough, its frequency adjustment range should be wide enough. In this way, the amplitude of the mid-range signal will not change much during the change of the tone of the audio amplifier from the weakest to the strongest. Therefore, the output volume can be kept stable.The tone control circuit is mainly divided into a negative feedback tone control circuit and an attenuation tone control circuit. For the former, the noise and distortion are relatively small, and its corner frequency is basically unchanged, but the slope of the characteristic curve will change accordingly. For the latter, the range of pitch adjustment is wider, but the noise and distortion are greater.3.3 Power Amplifier CircuitFunction: To provide the required power for the output load of the audio amplifier.Performance Indicators : distortion, frequency response, signal-to-noise ratio, and efficiency.Classification: OTL, OCL and BTL. OTL The OTL type is a push-pull power amplifier circuit with no transformer at the output end and only a large capacitance, which is a single power supply power amplifier circuit. It has the characteristics of small distortion, light weight, small size, and is conducive to integration. This circuit is widely used in audio amplifiers with low power output. OCL There is neither a transformer nor a large capacitor at the output end of the OCL circuit. It is a commonly used amplifying circuit for the dual power supply amplifier circuit. BTL The BTL power amplifier circuit usually uses a circuit without an output transformer. When the power supply voltage is low, the output load power is larger, which improves the utilization rate of the power supply. It is generally used when the output power is large.The application of integrated power amplifier is becoming more and more extensive. This is because the integrated power amplifier has the functions of small distortion, small size, light weight, low power consumption, high cost performance, overvoltage protection and noise cancellation.IV Introduction of Integrated Devices4.1 Integrated Op Amp NE5532The integrated operational amplifier NE5532 has strong output drive capability and good noise signal. It also has a higher power bandwidth and small signal. Therefore, NE5532 is a high-performance low-noise dual op amp operational amplifier.Equivalent Input Noise Voltage: 5 nV/√Hz Typ at 1 kHzUnity-Gain Bandwidth: 10 MHz TypCommon-Mode Rejection Ratio: 100 dB TypHigh DC Voltage Gain: 100 V/mV TypPeak-to-Peak Output Voltage Swing 26 V Typ With VCC± = ±15 V and RL = 600 ΩHigh Slew Rate: 9 V/μs Typ4.2 Integrated Power Amplifier TDA2030TDA2030 is a V-shaped 5-pin single in-line package structure. It has the characteristics of small transient intermodulation distortion, high rate of rise, large output power, small size and light weight. And it has over-current and over-voltage protection circuits inside.V Design of Audio Amplifier5.1 Design of Preamplifier CircuitNE5532 integrated operational amplifier has the advantage of high input impedance. Usually, the voltage series negative feedback circuit constructed with it is used as the first stage of the preamplifier. The voltage parallel negative feedback circuit formed by it is used as the second stage of the preamplifier. The circuit has strong resistance to common-mode signal interference and low output impedance.The design of the preamplifier circuit is shown in Figure 2.Figure 2. NE5532 Preamplifier CircuitAmong them,C9 and C1 are decoupling capacitors, their function is to eliminate low-frequency self-oscillation;C10 and C12 are high frequency filter capacitors;R5 and C7 determine the lower limit frequency of the preamplifier.5.2 Design of Tone Control CircuitThe audio amplifier adopts a negative feedback tone controller. The circuit design is shown as in Fig. 3.Figure 3. NE3352 Tone Control CircuitRp1: Bass adjustment potentiometer;Rp2: Tweeter adjustment potentiometer;C13: Coupling capacitor;C14: bass boost capacitor;C15: bass decay capacitor;C16: High pitch boost and attenuation coupling capacitor.among them:C16 should be much smaller than C14;Rp1=Rp2=200kR13=R14=R15=22k C14=C15=0.02μF Rp2=9R13.When the capacitive reactance is large, it is equivalent to an open circuit, and when the capacitive reactance is small, it can be regarded as a short circuit. Therefore, the capacitor C16 is equivalent to an open circuit, and adjusting the sliding rheostat Rp2 will not affect the bass adjustment.When the sliding rheostat Rp1 moves to the left end, the capacitor C14 can be regarded as a short circuit. For the bass signal, the capacitance of the capacitor C15 is relatively large, which can boost the bass signal.When the sliding rheostat Rp1 moves to the right end, C15 can be regarded as a short circuit, and the circuit can be used to achieve the effect of bass attenuation.The capacitive reactance of C14 and C15 is small relative to the tweeter signal, which is equivalent to a short circuit. When the sliding rheostat moves to the far left end, the tweeter signal can be boosted, and when Rp2 slides to the far right end, it plays the role of treble decay.5.3 Design of Power Amplifier CircuitThe integrated power amplifier has the characteristics of simple circuit, low price, and stable operation. The design in this blog uses the TDA2030 integrated circuit with excellent performance, which has the advantages of low harmonic distortion and overheating protection. The circuit is used as an OCL power amplifier, as shown in the figure. The function of the diodes D1 and D2 in the picture is to protect the circuit. On the one hand, it is to prevent the polarity of the power supply from being reversed; on the other hand, it is to limit the amplitude of the input signal. The output phase shift correction network is composed of resistor R22 and capacitor C22 so that the load is equivalent to a pure resistor. The lower limit frequency of the power amplifier circuit is usually determined by the input coupling capacitor C17. Capacitors C19 and C20 are low-frequency and high-frequency bypass capacitors respectively, and resistor Rp3 is a volume adjustment potentiometer.Figure 4. TDA2030 Power Amplifier CircuitVI Sound Amplifier SimulationUse Multisim software to simulate the audio amplifier. As shown in Figure 5. Test whether the operating voltage of each operating point is consistent with the theoretical value, and adjust the parameters of the circuit based on the obtained test results.

It can permit collector current up to 800mA and as well has power intemperance of 652mW.  Due to this, it is used for larger loads then BC547. So if you are considering for an NPN transistor which can switch loads of large current user,  then PN2222 will be the right option for your industrial developments.PN2222 Working PrincipleLike other transistors, PN2222 can be used as an amplifier and switch. Voltage crossways of base and emitter are six volts, so we have to apply these voltage crossways base and emitter to persuade a base current of the transistor. This will change it to forward biasing and consequently completions the linking between collector and emitter. One important thing in this circuit is the base resistor which is a current preventive resistor. This resistor in the circuit is for limit the coming current which can damage the transistor. Its value can be found by the given equation.RB = VBE / IBTo mark things modest, I have exposed a basic circuit of the transistor as a switch. In a real circuit, alterations must be vital. In this circuit, I supplied five volts to the base and 1K resistor to limit the current.Notice that in this circuit motor consumes around 500mA by the 12V supply source, meanwhile the PN2222 rating of the collector up to 800mA, which shows the importance that if we have BC547 in the circuit it would be damaged.PN2222 ApplicationsIt is used where higher current consumer loads in the circuit.It is used in numerous swapping submissions.It used to control the speed of different types of motors.It used in inversion and rectification circuits.It also used in Darlington pairs.PN2222 PackagePN2222 Popularity by RegionPN2222 ManufacturerON Semiconductor is driving energy efficient innovations, empowering customers to reduce global energy use.
