Application of integrated circuit TDA2822
Source: InternetPublisher:同住地球村 Keywords: integrated circuit TDA2822 switch speaker Updated: 2021/10/26
The working principle of this machine is as follows: Turn on the switch S. When the opposite microphone MIC speaks, the audio voice is input from the ⑦ pin of
the integrated circuit TDA2822 via ciRP . After being amplified by the internal BTL power amplifier circuit, it is sounded by the speaker BL - the pronunciation
is clear. Bright, and the volume can be adjusted by the potentiometer RP.
