Dear support team,


I have a question about power line.


ADAU1401A makes core voltate(1.8V) from 3.3V.



If 3.3V power line goes down to arround 2.5V, is core voltage gone down? or does it remain 1.8V?



At Q1 situation, if core voltage remains 1.8V, does ADAU1401A need external reset assertion or not?

(when 3.3V lien gose up to 3.3V from 2.5V, does ADAU1401A operation is normal without external reset assertion?)


Best regards,
