ELECTRICAL CHARACTERISTICS (continued)

(VDD = +3V to +3.6V, REF+ = 3V, REF- = GND, Read Mode (MODE = GND), TA = TMIN to TMAX, unless otherwise noted.)

Note 1: Accuracy measurements performed at VDD = +3.0V. Operation over supply range is guaranteed by power-supply rejection test.

Note 2: Guaranteed by design.

Note 3: Power-down current increases if logic inputs are not driven to GND or VDD.
