Amplifier Simple Circuit Diagram Stereo. The amplifier circuit diagram shows a 2 5w 2 stereo amplifier. 1 2w super small tda7052 tiny stereo audio amplifier for mobile or ipad.

Tda2822 stereo amplifier this is a stereo power amplifier. This is the diagram of this simple amplifier. The circuit is a simple two transistor pre amplifier using a feedback loop for enhancing the amplification.

You can also make a 5w mono amplifier out of it.

Tda1553 is a monolithic class b audio amplifier which contains 2 x 22 watt amplifiers in bridge tied load configuration. Here are the full schematics of a simple audio amplifier. So you will find extra humming noise in the amplifier. Any music as we know is in the form of a consistently varying frequency therefore when such a varying input is applied across the indicated c1 end terminals the same is delivered across the base t1 and ground.
