Where can I find information about the die surface for various ICs? I'm thinking about opamps in the first place.
The surface area is of course dependent on the features of the ICs (for opamps rail to rail, speed, noise) and on the max current they can handle. I think the process technology affects digital electronics, but not much analog circuitry.
So, where can I find the surface area for various common ICs and especially opamps?
This is out of curiosity, I don't have a need for any project.
