Electrical Characteristics Unless otherwise specified: C
VBAT = 1 µF, IOUT = 1 mA, CVDDB = 1 µF, CVDDA =
1 µF. Typical values and limits appearing in standard typeface apply for T
A = 25˚C. Limits appearing in boldface type apply
over the entire ambient temperature range for operation, −30˚C to +85˚C. (Notes 3, 4)
