AD7798 - Power Sequence

Question asked by Mr.K on Sep 19, 2012

I would like to know the power supply sequence of AVDD and DVDD for AD7798.

Does AD7798 have the power-up sequence in AVDD and DVDD?


Only when ADC is used, I want to turn on AVDD, And DVDD is always turned on.

I know AD7798 supports the power down mode. However, I want to turn ON/OFF the AVDD.

Is there a problem in this usage?
