CMOS TEMPERATURE SENSOR IC
S-5815A/5816A Series
The S-5815A/5816A 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.
