Hello everyone!
For my circuit, I needed a precision reference buffer, and I am using OPA197 to suit my needs. I have found a paper by TI (link) describing how to build a buffer reference, but one part is still unclear. Here's what the paper suggests:
While the paper explains how to select the Riso value, it doesn't shed any light on the Rf and Cf selection. The references setion is no use - the links don't work and I can't find the documents online.
So here is my question - how do I select Rf and Cf?
Thanks in advance!
