amplifier – TDA Audio Amplfier’s SVR/MUTING pin (pin3) – Electrical Engineering Stack Exchange

You can mute it again by just discharging the capacitor with a transistor switch, I think. The capacitor has two behaviors: 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 check TDA for a more thorough explanation on how it is supposed to work. As the capacitor charges, it reaches a specific voltage and an internal comparator halts the muting effect. I think they’ve managed to combine these two functions into one by using a capacitor. When the voltage at the pin is close to ground, the output is muted.

When power is applied, you could hold pin 3 low for x seconds using a RC circuit or a voltage regulator or voltage supervisor or a tdx7262, 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. The device is switched off until pin 3 reaches 0. As to the thump, that requires a sort of logic to make happen.
