HIGH-PRECISION TEMPERATURE SENSOR IC
S-8120ANP
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.
