When the voltage at the pin is close to ground, the output is muted. Post as a guest Name. I found something that said its to eliminate the thump the speaker gives off when power is applied or removed to and from the amplifier.

You can mute it again by just discharging the capacitor with a transistor switch, I think. You can check TDA for a more thorough explanation on how tda72662 is supposed to work. If pin 3 is disconnected or grounded, the amplifier output is disabled. Doing the same when power is disconnected is much more complicated.

As to the thump, that requires a sort of logic to make happen. You could run an RC filter to the supply voltage to get a power on delay.

If pin 3 is connected to at least 0. The device is switched off until pin 3 reaches 0.

I’ve done my research on it but I cant find much. This question has answers that may be good or bad; the system has marked it active so that they can be reviewed.

When power is applied, you could txa7262 pin 3 low for x seconds using a RC circuit or a voltage regulator or voltage supervisor or a microcontroller, enough time for the main voltage to stabilize and for the amplifier to be fully on. I must design a pcb with datasheet specifications but I don’t understand pin 3 and the 0.

I think they’ve managed to tda72262 these two functions into one by using a capacitor. It’s not the same IC but the function is similar.
