tpa3122d2 BTL configuration with some modification

Other Parts Discussed in Thread: TPA3122D2

Hi,

I've just come across an issue related to BTL configuration of tpa3122d2 power amplifier.

I configure it as BTL mode except that i ground the minus input, which means i only one channel input signal.

i power the circuit with 15V power supply and there is no sound output.

i checked the circuit connection and it seems not an issue with routing.

not sure if it has something to do with the fact i only used one input signal and ground another.

does anyone have similar experience or know what the problem is ?

Cheers

Jensen
