exposed Die Attach Paddle
[1] HXQFN16 package supply ground is connected to both GND pin and exposed center pad. GND pin must
be connected to supply ground for proper device operation. For enhanced thermal, electrical, and board
level performance, the exposed pad must be soldered to the board using a corresponding thermal pad on
the board. For proper heat conduction through the board, thermal vias must be incorporated in the PCB in
the thermal pad region.
