S-5813A/5814A Series www.ablic.com CMOS TEMPERATURE SENSOR IC www.ablicinc.com ABLIC Inc., 2006-2015 Rev.4.1 02 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 100C. 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.
