Note: Resistance characteristics are given for the sensor only.
Absolute Maximum Ratings*
Power Supply Voltage (V

) ................................-0.3V to 4.6V
Storage Temperature (T
stg
) ............................. -40° C to +85° C
*NOTICE: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
device reliability.
