SENSOR INTERFACE ELECTRICAL CHARACTERISTICS

Unless otherwise noted, VIN_A = 3.6V, CIN_A = 1 µF, CIN_B = 100 nF, CIN_C = 2.2 µF, CSEN= 1 µF, HWEN = high. Limits in

standard typeface are for TJ = 25°C, and limits in boldface type apply over the operating ambient temperature range (−30°C

to +85°C).
