Hi team,
My customer is using AD7401 from ADI and AMC1204B for performance comparison in below SCH:
However, when using AMC1204B, the error is large(>10%), while ADI part is small. Below data is captured for your reference. Can you help check if the SCH/ parameter is OK? Any angles we should look into? Thanks.
