TAS5634: Relation ship between PVDD and GVDD

Part Number: TAS5634
Other Parts Discussed in Thread: TAS5614LA, TAS5614

Hello Expert,

I'd like to confirm about whether we can use this device with case that GVDD voltage is higher than PVDD voltage.
As far as my understanding, there isn't any limitation between PVDD and GVDD on datasheet.
For example, is there any issue when I use this device with PVDD=12V and GVDD=13V case?

Best regards,

Hi,

It should be no problem.

Is the PVDD=12V a transient condition or constant condition? If it's constant, you can choose devices like TAS5614LA, TAS5614 to be more cost effective.

Thanks!

Regards,

Sam

Hi Sam,

Thank you for your swift reply.
I understood there isn't any problem with this use case.

Also, fortunately, this is not constant condition.

Best Regards,
