VSS
Ground input (the thermal pad on the underside of the package) There is an internal electrical connection
11
–
between the exposed thermal pad and VSS pin of the device. The exposed thermal pad must be
connected to the same potential as the VSS pin on the printed-circuit board. Do not use the thermal pad as
the primary ground input for the device. VSS pin must be connected to ground at all times.
