    Hi Dr. Chandra, Yes, you may use the OPA392 or OPA397 as an alternative solution to the OPA376.

    One more comment to those who may come across this thread. What I initially failed to notice was that, according to docs, OPA392 maintains low I B (-20/+30fA) within V CM =±1.5V range (is it relative to V S /2 ?) and above V CM =1V I B+ goes through the roof…

    I believe R2 is just a current limit for SD1 and has no specific design value. i.e no gain function. My final circuit turns this into a peak detector. Turned it into a single supply by using the REF2041 as the 2.048V amplifier mid point reference and…

    Hi Ohad, The OP07 is a good, low-cost amplifier, but does have limited input and output range capability (input common mode needs to be 2 V higher than Vcc-). Depending on the input common-mode voltage, it may not work. Typically, for operation at 3.3…
