SENSOR INTERFACE ELECTRICAL CHARACTERISTICS
Unless otherwise noted, V_{IN_A} = 3.6V, C_{IN_A} = 1 µF, C_{IN_B} = 100 nF, C_{IN_C} = 2.2 µF, C_SEN= 1 µF, HWEN = high. Limits in
standard typeface are for T_J = 25°C, and limits in boldface type apply over the operating ambient temperature range (−30°C
to +85°C).
