AC Electrical Characteristics

The following specification apply for V+ = +3.0V

DC to +3.6VDC, unless otherwise specified. Boldface limits apply for

A =TJ =TMIN to TMAX; all other limits TA =TJ = 25 ˚C. The SensorPath Characteristics conform to the SensorPath specifi-

cation. Please refer to that specification for further details.
