Hi Jimmy,

The three potential replacements we recommend for this part are the OPA3355 and OPA3690. They are not pin to pin but have similar functionality.

Best Regards,

Ignacio

Hi team,

But base on customer's test that can not meet spec. due to OPA3355 spec worse than ADI.

Customer main spec are slew rate and BW and rail to rail.

Hi Jimmy,

I attached two sets of lists of devices that could work and are comparable to the competitor device. The first list covers devices that are at or beyond the BW and SR performance of the competitor device but are not rail to rail out. The second list highlights devices that are rail to rail out but do fall short of the BW and SR performance of the competitor device.
