    Temperature coefficient of SAR ADC

    sainer
              What is the temperature coefficient of SAR ADC?. For Delta Sigma it is written 0.55 uV/degreeC, but for SAR ADC I couldn't find it on datasheet.

          Datasheet lists the variation of Vref with temperature, so you can take that into account.

            That of course is not the actual SAR converter front end drift. For that you would

               

            need to file a CASE as its not in the datasheet as you have discovered. It may be wrapped

               

            up in the overall performance spec.

               

             

               

            It would be great if you post back the answer you get to benefit all.
