CMOS TEMPERATURE SENSOR IC

S-5815A/5816A Series

Seiko Instruments Inc.

1

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.
