Hello,
I am evaluating the AD4195-4 for a precision measurement application using the internal PGA.
I found the offset drift specification in the AD4195-4 data sheet, but it appears to be specified for chop disabled conditions.
Could you please let me know if any offset drift data is available when chop is enabled?
The main condition of interest is as follows:
For reference, we are also comparing the AD4195-4 against the TI ADS124S06.
The ADS124S06 data sheet provides offset drift specifications with Global Chop enabled. However, from a linearity / INL point of view, we are interested in evaluating the AD4195-4 as a possible alternative.
To make a fair comparison, we would like to understand the expected offset drift performance of the AD4195-4 when chop is enabled.
If there is no guaranteed specification for offset drift with chop enabled, could you please provide any characterization data, typical expectation, or guidance on how to estimate the drift improvement when chop is enabled?
Best regards,
