I would expect it to be very small since the ADA4522 is a zero drift amplifier that uses a chopper architecture which continuously self correct any dc error over time and temperature. Let me check it to the product owner if they have actual data or estimate.
So far, these are the opamps available which has a long term drift specs on its datasheet.
Just an update, there is an ongoing characterization of the long term drift of the ADA4522 and we would be able to publish the data in a few months once the testing is complete. If you want to see data from zero drift amplifier part, then feel free to check the LTC2057 datasheet.
For one of my project (designing a low drift voltage source), I have the same question as Ben.
I know that this post is pretty old, however, have you published the results of the characterization of the long term drift of the ADA4522 ? Would you be able to share more information ?
