CMOS TEMPERATURE SENSOR IC
Rev.5.1_00
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.
