Hi, i would like to know the OP296 input resistance. I was wondering if the OP296 works as a transimpedance amplifier with a 1M feedback resistance (so i need that value). any advice?.
And the same question for ADA4528.
How were you going to use input resistance? It's generally of limited usefulness
and for a voltage follower, the input resistance is bootstrapped by the open loop gain
at that frequency. For error calculations, input bias current can be used.
I would not do a new design with the OP296 which came out in 1995. I would use the next generation,
