RE: ADS131M08: Circuit design checked
Rohit6230, I don't have to many comments for this schematic. First, the output capacitance of the
REF5020
should be from 1uF to 50uF. However, you have about 70uF of bulk capacitance on the REF2.048V node. I would reduce the output capacitance...

RE: ADS131A04: ADS131A04 with external reference source
Lukasz, To be honest, I don't have enough information on that. I don't think we have that specific characterization on the op-amp. It is likely that it would work fine if you made the replacement with the
REF5020
for room temperature operation...
