Hi Herbert,

Yes. Here is the related PCN,

The new FAB in TL082IDR has smaller Si-die than the pre-PCN op amp, which is what you found. 

There are some minor differences between pre-PCN and post_PCN op amp in terms of GBW and open loop output impedance. Please check for the op amp's compatibility and difference in functionality. If you see any possible op amp behavior issues, I can help you to compensate for the differences. 

If you have other questions, please let me know. 

Best,

Raymond
