AD7701 self-calibration

Are there any known issues with the AD7701 self-calibration (SC1 & SC2 low) going to the AIN instead of the AGND?

  • Thanks.  There have never been any provisions/revisions to use anything other than the self-calibrate from the initial design. The clock timing is due to power up issues.  Sometimes the CAL is attributed prior to the clock being there.

    Are there any revisions notes or errata for the AD7701?  The specsheet is on rev e so that would imply some changes, correct?
