High Gain Instrumentation Amplifier

Question asked by kooshar on Aug 6, 2012

I intend to amplify differentail inputs of few micro volts in amplitude into milli volts. These signals fluctuate and thus are not DC.

And their BW is between 100Hz and 100kHz.

I am looking for an Instrumentation Amplifier that can perform high gains, i.e. 10kV/V or higher.

Ideally, I need a 20kV/V amplification. Otherwise, will use atwo-stage design.

The amplifier can be run at 3.3V or 5V, single supply.


I appreciate ADI part numbers, comments/recommendations, and sharing similar experiences.
