OP296 input resistance

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.

Thanks.

  • Mateo,

       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,

    ADA4096-2.
