CMOS TEMPERATURE SENSOR IC
S-8110C/8120C Series
The S-8110C/8120C Series is a family of high-precision
temperature sensor ICs on a single chip with a linear
output voltage for temperature changes.
Each chip is composed of a temperature sensor, a
constant current circuit, and an operational amplifier.
It can be used at temperatures ranging from –40
°C
to
100
°C.
These devices have much better linearity than
other temperature sensors such as thermistors, and can
be used for a wide range of temperature control
applications.
