Asking for the TAS5753 PVDD and AVDD/DVDD sequence

SHH

Hi Team,
Customer is using and evaluating TAS5753.
Could the PVDD rise up before the AVDD and DVDD?
The AVDD/DVDD is buk form the PVDD.

Thanks,
SHH

Hi SHH,

In general the recommended sequence is the one in the datasheet. If the customer is unable to do this, however, there will likely be no issue in powering up PVDD first as long as /RESET and /PDN are kept low until all power supplies are stable.

Regards,

Alex
