14 watts TDA2030 Stereo amplifier circuit

14 watts TDA2030 Stereo amplifier circuit 

This is a TDA2030 stereo amplifier circuit. It is a special project. Because it is an OCL type amplifier. Which provide power driver of 14 watts/channel at load 4 ohms. So, 

it is suitable for beginners thought will build electroacoustics to listen to themselves. 

This project use IC of The SGS company number TDA2030.

 Which SGS said that TDA2030 is a power amplifier IC in 5 pins form. 

9 The Setting circuit on a class AB power amplifier to the output of the high harmonic distortion and low crossover. They are ready,

 shock output protection, and the temperature is too high,

 complemented within the integrated circuit

Technical Specifications of IC-TDA2030 

● Maximum voltage supply used of +/- 18VDC.

 ● Begin working at a minimal voltage of +/- 6VDC.

 ● Power driver output 14 watts at 4 ohms and 9 watts at 8 ohms.

 ● The maximum current of 900mA. 10 

● Frequency response range 10HZ-140KHz at -3dB. How this circuit works In the circuit, the figure is a single channel amplifier. You will see that have very few parts. Both pin 1 and pin 2 of IC-TDA2030 input. The pin 1 is non-inverting input and pin 2 is inverting input. Then input of power amplifier comes to C1 into pin 1 of IC. 

● The R3 determines the input impedance of the IC. 

● Pin 3 is -VCC leg or negative voltage, and pin 5 is a +Vcc or positive voltage. 

● Four capacitors C3, C4, C5, and C6 are bypass filter voltage +Vcc and -Vcc. 

● R1 as acts adjust the gain of IC with a negative feedback form. If R1 has higher resistance. Then, the gain rate of IC rises up as well. 

● The R4 and C7 are protectors a oscillated high frequency. How to build First of all, you need to have all components list below. Parts you will need 11 MONO form IC1: TDA2030 18W hi-fi amplifier and 35W driver D1, D2: 1N4007, 1000V 1A diodes D3-D6: 1N5402, 200V 3A diodes
