OP27 Spice model

Question asked by florentd on Sep 16, 2016

  1. Is the spice model of the OP27 include thermal deviation of offset voltage? Is the noise is implemented?
  2. Is the spice model of the OP27S exist?

 My Orcad simulation (OpAmp buffer positive input grounded) doesn't show a 40µV variation
(min) with a 100°C variation as specified in the datasheet (0.4µV/°C).
I only see a 100 µV offset with a variation of 40fV between -20 and 80°C.
Furthermore, there is no trim pins:  as specified in the datasheet, Rp needs to
be at least 8000 Ohm. Is it normal?
