Note 1: Accuracy measurements performed at VDD = 3.0V, unipolar mode. Operation over supply range is guaranteed by power-

supply rejection test.

Note 2: Bipolar tests are performed with VREF+ = +1.5V, VREF- = -1.5V, VSS = -3.0V.

Note 3: Unipolar input range, VIN = 3.0VP-P, WR-RD mode, VDD = 3.0V

Note 4: Guaranteed by design.

Note 5: Power-down current increases if control inputs are not driven to ground or VDD.

ELECTRICAL CHARACTERISTICS (continued)

(Unipolar input range, VDD = 3.0V to 3.6V, GND = 0V, VSS = GND, VREF+ = 3.0V, VREF- = GND, specifications are given for RD

mode (pin 7 = GND), TA = TMIN to TMAX, unless otherwise noted.)
