    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...
