About EPAD of ADA4622-2


I need some help.

As below picture picked from the datasheet.


The EPAD of 2ch Version(ADA4622-2)  is recommended to connect the EPAD to V+, but the note for  4ch version(ADA4622-4)  said [the exposed must be connected to V+].

So, is it a must connecting EPAD to V+ for ADA4622-2?

If it is just recommended, can I connect EPAD to GND?

Best Regards,
