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: VDD1 is the voltage measured at DGTL VDD1 with respect to DGND1. VDD2 is the voltage measured at DGTL VDD2 with respect to the
DGND2. VDD3 is the voltage measured at ANLG VDD with respect to AGND. For these specifications, all ground terminals are tied
together (and represent 0 V). When VDD1, VDD2, and VDD3 are equal, they are referred to simply as VDD.

NOTE 2: Analog input voltages greater than that applied to REF+ convert to all 1s (1111111111), while input voltages less than that applied to
REF– convert to all 0s (0000000000). The total unadjusted error may increase as this differential voltage falls below 4.75 V.
