In this article, you will learn, how to make a simple stereo audio amplifier with the TDA2822M. The total cost of the components is less than 5$ and because the circuit is very simple you can make it on PCB, or on a protoboard.
TDA2822 Audio Amplifier
TDA2822 is a dual op-amp low voltage audio amplifier. It is an 8 pin IC with 2 outputs. You can make use of individual op-amps of IC. Its features are the low crossover distortion, low quiescent current, stereo or bridge configuration and the supply voltage is down to 1.8V. In this project, I designed the stereo amplifier.
