TAS5760M: About TAS5760 PBTL output polarity

GW
Intellectual 2350 points
Part Number: TAS5760M

Hi, Team

Our customer use TAS5760M in their speaker project, PBTL configuration.

I check below E2E history,  in PBTL mode, Port B is the positive and Port A the negative.

But our customer prefer to check whether we have any i2c register to invert the polarity in PBTL, they prefer "Port A is the positive and Port B is the negative.", since the PCB is fix, they can not change the PCB.

Do u have any suggestions?

Thanks.
