ADS5294: ADS5294 power sequencing requirements

Part Number: ADS5294

Tool/software:

Are there any specific power sequence requirements? I have inherited a design where AVDD and LVDD are supplied from separate regulators with a programmable delay (currently time together). At present, I have a board where the LVDD regulator has a fault and is not being enabled. Will powering AVDD with LVDD held at 0V stress the device?

  • Hi,

    Why do you want to use in this condition . It is logical to fix the regulator and start using the board.

    Datasheet does not have any particular supply sequencing . So AVDD at 1.8 with LVDD at 0 should not cause any unwanted effect.
