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 4: When binary output format is used, analog input voltages greater than that applied to REFP convert as all ones (1111111111), while input
voltages less than that applied to REFM convert as all zeros (0000000000). The device is functional with reference down to 1 V.
(VREFP − VREFM − 1); however, the electrical specifications are no longer applicable.
