SYMBOL MIN TYP MAX
Note 1: Accuracy measurements performed at V
DD
= 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, V SS = -3.0V.
Note 3: Unipolar input range, V IN = 3.0V P-P , WR-RD mode, V DD = 3.0V
Note 4: Guaranteed by design.
Note 5: Power-down current increases if control inputs are not driven to ground or V
