Rev.4.1_00
The S-5813A/5814A 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.
The operating ambient temperature is 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.
