Stereo TDA2822 audio power amplifier circuit

Stereo TDA2822 audio amplifier circuit
In this series I use IC tda2822M as the main amplifier, but if you want to use in addition to IC TDA2822M you can use ic I mentioned this is KA2209, NJM2073, U2822B, U2823B. Output is issued no more than 4W, which had low output. Supply voltage from 3 volts to 16 volts.

Below its schematics of TDA2822 stereo audio power amplifier
