Read More…This DIY kit uses the TDA2822M chip which is developed by the ST. This kind of chip is widely used in the WALKMAN, the radio and the Multimedia active speaker as the Audio Amplifier. It has the advantage of simple circuit, good Sound volume,Wide voltage range and so on, what's more, it can works in the stereo and the BTL circuits.
The main circuit is very simple which is consists of the audio input adjustment circuit and the TDA2822 audio amplifier circuit. The audio input adjustment part is mainly consist of the headphone seat and the turbine rotary potentiometer, Besides, it controls the size of the audio signal by adjusting the potentiometer.
