Audio Amplifier Circuit Diagram Using 741. A specialty audio amp chip is way less work and the lm386 gets you 1 2 watts with very little effort. Separate from that mrchips is right.

In the circuit diagram opamps labeled a1 and a2 are the input buffers. The distortion of less than 0 5 and has a bandwidth of over 20khz. A specialty audio amp chip is way less work and the lm386 gets you 1 2 watts with very little effort.

Separate from that mrchips is right.

This variable resistor helps in adjusting the amplitude voltage level of the input audio signal so it also adjusts the volume of the output signal as well. The above circuit diagram shows how the ic 741 can be configured as a high power amplifier circuit. In an ic 741 operational amplifier pin3 and pin6 are input and output pins. More than two inputs can be used.
