Low-drift Instrumentation Amp

[emsensors]

Well, this is a follow-up post following a question about the INA111. Really, I don't need an actual answer to this question, more advice on the best place to go to help me. So, I am looking for a zero-drift instrumentation amplifier that I can operate at 10 kHz with a gain of at least 100. I'm looking for good CMRR, more important, low drift in CMRR. I would like +/-5V to +/-15V supplies but I'll take what I can at this stage. I find it very hard to serach for all these criteria - has somebody put a comparsion together that covers all manufacturers? Any advice on how best to serach??? Or can somebody just come out and tell me a part number that will solve all my problems?

Cheers!

Are you sure it is CMRR drift that you are concerned about, not gain drift? Starting a new thread on the same topic doesn't seem a good idea.
