Mukuno-san,
The input impedance parameters for a CMOS op amp such as the OPA4197 are only measured at the time of initial characterization, and even then because they are so tremendously and variable between lots that only typical numbers are provided.
These input impedances are so high that any variance in them is of little consequence in practical op amp application circuits.

Perhaps on the R values Tom, but maybe Mukuno-san is looking for a max input capacitance - this can play havoc with some circuits.
Also, usually none of this measured, but comes out of designer sims - kind of a hard measurement, but the design sim can run worst case - but rarely done for these parameters/
Hi Muk,
We haven't heard from you in a while, we hope the issue was resolved. I am closing this thread now, reply to re-open if you have any additional questions.
Mukuno-san,
We are glad to have assisted you with your OPA4197 inquiry. Please close this e2e inquiry.
Thank you, Thomas
