HI, Folks

I could not find any power sequence requirements for ADS7863A.

Does ADS7863A allows all combination of BVDD and AVDD except BVDD<(1.5 × AVDD)?

Hello Keiichi Kajino,

Indeed, the only requirement is that, if BVDD starts ramping first, then its value should never exceed 1.5 times the value of AVDD. For example, applying BVDD while AVDD is still zero volts would be a violation of the absolute maximum rating s of the part.

Hope this helps.

Best regards,

Jose
