The TJ-263 DAP is used as a thermal connection to remove heat from the device to an external
heat-sink in the form of the copper area on the printed circuit board. The DAP is physically
connected to backside of the die, but is not internally connected to device ground. The DAP should
be soldered to the Ground Plane copper.
