I am working on my B.Sc. thesis and I'm having the trouble finding the SPICE model for this (relatively new) op amp ADA4523-1 even though the product website said it is available:https://www.analog.com/en/products/ada4523-1.html#product-tools
My final goal is to find 1-2 new precision op amp models that out-perform the old OP27. Then compare these op amps to prove how much the industry standard has improved overtime.
Thank you very much. Any suggestions would be welcome.
ADI offers a vast portfolio of precision opamps. Particularly for the OP27, the new alternative part recommended is ADA4004-1 which has available spice model in LTspice and in the product page. I think you can use that as a starting point. ADA4523 is a zero-drift opamp and prior to that the latest zero-drift is ADA4522 which has also spice model both in LTspice and on its product page. Also, the comparison will likely depend on the specific application which you will use these parts.
