OPA855: OPA855: connection between thermal pad and V- pad

Part Number: OPA855

Hello,

Would anyone be able to explain why the thermal pad has to be connected to the negative voltage supply?

The reason for this question is that I just designed and purchased a PCB where I forgot to connect thermal pad and V-. I was therefore wondering if I have any chance my device to work nonetheless or if instead these pads must be connected?

Many Thanks,

Francesco
