S-5814A

S-5813A/5814A Series www.sii-ic.com © Seiko Instruments Inc., 2006-2015 CMOS TEMPERATURE SENSOR IC 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.  Features Temperature accuracy Linear output voltage Nonlinearity Wide power supply voltage operation Low current consumption Built-in operational amplifier Output voltage referred to VSS Lead-free (Sn 100%), halogen-free S-5813A Series : ±5.0°C (–30°C to +100°C) S-5814A Series : ±2.5°C (–30°C to +100°C) –11.04 mV/°C typ.
