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.
