† 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 under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: All voltage values are with respect to the GND terminal with REF – and GND wired together (unless otherwise noted).

NOTE 2: Analog input voltages greater than the voltage applied to REF+ convert as all ones (111111111111), while input voltages less than the

voltage applied to REF– convert as all zeros (000000000000).
