Greetings,
I'd like to invert a signal I get from a photodetector (the signals are up to 100 mV). I decided to use an inverting op amp circuit for that, however, when looking online through the op amp catalogs - the minimum input voltage in the descriptions is a few volts while my input would be in the range of mV. Would that be a problem? Is that only a recommended range given there? I do realize I will get some noise in that case, however, I'll make sure to pick op amps with the optimal slew rate, offset voltage and bandwidth for my needs.
Thanks for any advice.
