S-8120C

S-8110C/8120C Series www.sii-ic.com © Seiko Instruments Inc., 2002-2015 CMOS TEMPERATURE SENSOR IC Rev.5.1_00 The S-8110C/8120C 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.  Features Temperature accuracy S-8110C Series: ±5.0°C (–30°C to +100°C) S-8120C Series: ±2.5°C (–30°C to +100°C) Linear output voltage –8.20 mV/°C typ. Ta = −30°C: 1.951 V typ. Ta = +30°C: 1.474 V typ. Ta = +100°C: 0.882 V typ. Nonlinearity ±0.5% typ.
