My customer has strong concern about connection of thermal pad (PowerPAD) of OPA561. These are some descriptions on this on data sheet, but those don't agree. Could you help us deal with it?

I agree that the wording in this data sheet is somewhat misleading. The answer to your question is that the OPA561 flag pin should be electrically connected to most negative supply (V-). This is to prevent a mismatch in substrate bias that can lead to performance issues or even damage to the device.
We will fix this discrepancy in the data sheet to avoid confusion in the future.
