Hi Andromeda8 ,

Connecting the exposed pad to ground is not always the case, it depends on the part. Normally not electrically isolated, it typically needs to be connected to a ground or power plane, depending on the device. I would always recommend following the datasheet. For the LT6226, the EPAD must be connected to ground for single supply, and V- for dual supply configuration.

Here are some links that may help you with your question:
