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¡C (300 K) and

increases by 10 mV/¡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.
