The LMV321 is made at different assembly sites, so it is possible to see differences.

The TLV9001 is compatible with the LMV321.

Hello Li,

LMV321 had a PCN (product change notice) that added a new fab process and design.

Partial PCN below. The left die is this new fab process and design.

Let me know if you have any electrical issue with left die. I expect you do, why else would you look at the die?
