Part Number: PCM1794A
Other Parts Discussed in Thread: OPA4197

Hi teams,

My customer want to design PCM1794A.

It need to perform IV conversion, since its output is a current.

When IV conversion was carried out with OPA4197, the output get a noise about a few mV.

Please let me know how to reduce for this noise.

Best regards

Hello Hayashi-san,

Do you think you could share a schematic on how they are using the op-amp? In this application the discrete components selected for can also impact performance, do you have access to a bill of materials as well?

Thanks!
Paul
