Not internally connected.
36, 37, 47
Connect to AGND and PGND – should be star point for both grounds.
Internal resistive connection to AGND and PGND. Thermal vias on the PCB
Thermal Pad
-
should connect this pad to a large copper area on an internal or bottom
layer for the best thermal performance. The Thermal Pad must be soldered
to the PCB for mechanical reliability.
