Hi support team all

When in hold mode, if VA changes during data conversion, will it affect the converted data?

I thought that the compared VA/2 was also sampled internally, but I thought that might be a mistake, so let me confirm.

Best regards,

Hi Daisuke,

Yes - it will have an impact. Changes on VA will impact the LSB size, so its important to keep the reference (VA supply) stable throughout the conversion process as well as between conversions.
