3.TDA2822 main electrical parameters The main electrical parameters of the TDA2822 and TDA2822M has some points of differences. The main electrical parameters of the TDA2822 and TDA2822M are as shown in table 7. Table 7 The main electrical parameters of the TDA2822 and TDA2822M 4. Signal process The signal gets into the IC by TDA2822M's pin-6 and pin-7, and the signal is amplified by the power amplifier then output by pin1 and pin3 to promote the speaker or headphone. In this circuit, the Joubert network of the left and right channel power amplifier is composed of the C5, R3 and R4, C6. 5.Troubleshooting tips If the left and right channels are silent, and the power supply between the TDA2822M's pin2 and the ground is normal, then it is mostly the TDA2822M's own fault.
