Hi Sir,
Is there any risk of having audio signal at the output pins (OUTR/OUTL) when the TPA6132 in OFF state?
Thanks, Ian.

Hi Ian,
Please take a look at this previous thread about the same kind of question: https://e2e.ti.com/support/audio/f/6/p/542240/1977304#1977304
This thread includes an app note about connecting external signal source to the outputs of some of our amplifiers. Let me know if you have further questions.

Hi Ivan,
Thanks for information.
As customer's application, TPA6132 is a stand alone PCB, external audio signal comes to speaker from another PCB and TPA6132 PCB will no power at the same time.
This application condition cannot be changed, Do you have idea how we can protect TPA6132 once audio signal comes from another PCB?
Thanks, Ian.
