Part Number: ADS7853


For the ADS7853, is it okay to have the Digital supply applied with the analog supply un-powered (0V?)

    Hi Steve,

    There are no specific limitations to the order of power supply ramp, so having DVdd up on the ADS7853 before the AVdd supply is okay. The only real limitation is that you cannot have the analog inputs applied before AVdd or the digital controls active before DVdd.
