2. Has the OFFSET function been cancelled after the wafer is changed

The offset adjustment feature in the post-PCN product has been removed and eliminated due to better FAB controlled process. This is a general  purpose op amp. If the lower voltage offset feature is desired, you may consider low Vos type of op amps, see the link below. In the precision op amp selection, there are low cost op amps in the catalog. If you need additional recommendation, please let me know.
