PCM5101A: Power Supply Sequence

Akio Ito

Part Number: PCM5101A

Hi,

A customer plans to use PCM5101A with 3.3V and 1.8V power supplies respectively for AVDD and DVDD.
Is there any problem if 1.8V is supplied after few seconds than 3.3V?

Best regareds,

Hi Ito-san,

There should not be a problem with started AVDD a few seconds before DVDD. Also, please not that LDOO needs to be supplied with 1.8V as well if DVDD is 1.8V.

Please let me know if you have any more questions.
