Hello,
We are using the OPA1622 for an amplifier application. When we use 2.2k input resistors, and 10k feedback resistors for a gain of 4.54x, the circuit performs flawlessly. However when we swap the resistors to 33k for the input, and 47k for the feedback, to achieve a gain of only 1.42x, we are having problems that we suspect is oscillation. Should this be expected? If so, what is the minimum gain that can be used for stable performance?
Thanks in advance!
