Tool/software:
The OPA2210 data sheet does not seem to indicate the appropriate connection for the thermal pad (WSON-8 package). Can you confirm that the pad is electrically isolated and thus connecting to a ground plane (e.g. midpoint between V+ and V-) would be appropriate ? Thanks !
The pad might or might not be isolated, but if it is not isolated, then it is connected to the most negative voltage, V−. See [FAQ] Where do I connect the power pad for an operational amplifier?
Hi Scott,
I agree with Clemens. I verified there is conductive die attach from the thermal pad to the bottom of the die, which means the substrate will be electrically connected to the thermal pad, and therefore needs to be biased to V-.

Thanks Chris. I see now that this specific question was asked and answered three years ago, but it wouldn't come up when I searched before posting. Thanks :)
Hey Scott,
No problem! Let me know if I can be of further assistance.
