CMOS TEMPERATURE SENSOR IC
S-8110C/8120C Series
Seiko Instruments Inc.
1
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.
