† Stresses beyond those under absolute maximum ratings may causr permanent damage to the device. This is a stress rating only, and functional

operation of the devise at these or any other conditions beyond those indicated in the recommended operating conditions section of this

specification 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 network ground terminal.

NOTE 2: Analog input voltages greater than or equal to that applied to the REF+ terminal convert to all ones (11111111), while input voltages equal

to or less than that applied to the REF– terminal convert to all zeros (00000000). For proper operation, the positive reference voltage,

VREF+, must be at least 1 V greater than the negative reference voltage, VREF–. In addition, unadjusted errors may increase as the

differential reference voltage, VREF+ – VREF–, falls below 4.75 V.
