OPA657: about the differences between OPA657U and OPA657UB

Part Number: OPA657

Hi.

I looked at the following threads and datasheets about the differences between OPA657U and OPA657UB.

https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/389036/opa657/1593655?tisearch=e2e-sitesearch&keymatch=OPA657UB#1593655

But I could not find the difference about the specs of these devices.
Sorry to trouble you, but could you please make a comparison table of specifications?

Best Regards,

Nishie

Section 7.6 of the datasheets lists all differences between the grades.

The OPA656 and OPA657 JFET input devices were trimmed for both offset and offset drift. They were also set up for a 100% ATE test for drift - very unusual in higher speed op amps, that table is here for the OPA657 - B versions where are the improved DC accuracy options, The OPA656 is unity gain stable, the OPA657 is decomped
