What is the Input Resistance of the OPA184?

pete_v on Apr 6, 2016

Hello community,

Title of the post says it all. I think I might be able to use this amplifier, but I have a requirement for Gohm+ R input.

Thanks

I've got the AD8610 in the circuit now, and it does well, as far as I've been able to evaluate it. Except that on the -5V input, there is a very noticeable 2-3% error. I think my input is too close to the rails.
