MISCELLANEOUS AND PACKAGE
14, 17 N/C — All N/C should be connected to the main system ground.
33 Thermal PAD — There is an internal electrical connection between the exposed thermal pad and the AGND ground pin of the device. The thermal pad must be connected to the same potential as the AGND pin on the printed circuit board. Do not use the thermal pad as the primary ground input for the device. AGND pin must be connected to ground at all times.
