AD8643 Thermal Pad Connection

This is a silly question, but what would happen if the AD8643 Thermal pad for LFCSP package is connected to Ground?


I think Pads are often connected to Ground, so while making a PCB design, I mistakenly connected it to Ground instead of V+ as specified in the datasheet.


The amplifiers seem to be working, but I have some issues with the overall circuit that I'm debugging. I wonder if this has any negative effects.


Thank you
