AS300
Shunt Temperature Sensor
Description
The AS300 is a two-terminal integrated circuit temperature sensor. It is
a precision-trimmed shunt type regulator that emulates a zener diode
in function. Its output voltage is linearly proportional to temperature in
Kelvin. The output voltage is calibrated for 3.000 V at 27隆C (300 K) and
increases by 10 mV/隆C.
The AS300 is available in four packages.The SOT-223 offers a large
heat-sink for transferring heat to the die for fast and accurate thermal
sensing. The SOT-223 is especially effective at sensing the tem-
perature of hybrid and MCM substrates. The SOT-23 is best-suited
for applications requiring a small footprint or precision force/sense
metering.
