Paul,
You probably want to build the input stage discretely if you want higher transimpedance gain. Instrumentation amplifiers normally have relatively low feedback resistors to minimize thermal noise for the typical voltage amplifier use case. You…

to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
