Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: If V
SS
is open-circuited with V
DD
and either AGND applied, the V
SS
pin will float positive, exceeding the Absolute Maximum Ratings.
A Schottky diode connected between V
SS
and GND ensures the maximum ratings will not be exceeded.
