Does anyone know if there is a spice model for the AD628 ?
Hello. Unfortunately we do not have an AD628 spice model readily available.
However, the AD629 is on the web. That spice model coupled with an op-amp at the output for additional gain can at least give
you a reasonable replacement in terms of functionality. Sorry we do not have the AD628 for immediate use.
Great, thanks for the assistance, will give it a try.
