The S-8110ANP is a ultra-small packaged high-precision temperature sensor IC that outputs voltage with a temperature coefficient of 8.5mV/°C, and is able to operate at 2.4V. A temperature sensor, a constant current circuit and an operational amplifier are integrated on a single chip. The operating temperature ranges from -40°C to +100°C. The S-8110ANP 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.

LOW VOLTAGE C-MOS TEMPERATURE SENSOR IC S-8110ANP n Definition of terms 1. Output voltage ( Vout )
Output voltage Vout
Output voltage Vout is defined as the voltage between measured pin-4 and Vss. Vout is linearly proportional to ambient temperature. S-8110ANP is tested for Vout at -30°C,+30°C and +100°C.

2. Temperature sensitivity ( Vse ) Output voltage Vout
Temperature sensitivity Vse is defined as the average slope of the Vout versus Ta curve using the following formula.
Vout(-30)
Vse =
{Vout(+100) - Vout( - 30)} 130
