LOW-VOLTAGE C-MOS HIGH-PRECISION TEMPERATURE SENSOR IC

The S-8120AMP is a ultra-small packaged high-precision temperature sensor IC that outputs voltage with a temperature coefficient of - 8.5mV/°C and a temperature accuracy of ±2.5°C. A temperature sensor, a constant current circuit and an operational amplifier are integrated on a single chip to be able to operate at 2.4V. The operating temperature ranges from -40°C to +100°C. The S-8120AMP is superior in linearity over conventional temperature sensors like thermistors. It can be applied to an ever expanding wide range of applications that call for high-precision thermal control.
