Hello, I need to simulate a circuit with AD8231, but I can't find any spice model for it. Can you give me a link to download it, or can I use any other similar IA and which?
Unfortunately we don't have a spice model available for AD8231. Also, we don't have a SPICE model that is close enough to the AD8231's performance. However, if you would like to simulate a three-opamp instrumentation amplifier behavior, you could choose from a few for which we do have SPICE models available: AD623, AD8235 or AD8221. Note that none of these have programmable gain or implement zero-drift techniques like AD8231.
You can perform a search for SPICE models from the following link:
