S-8110ANP rev.1.01
LOW VOLTAGE C-MOS TEMPERATURE SENSOR IC
S-8110ANP
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.

Definition of terms
1. 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 )
Temperature sensitivity Vse is defined as the
average slope of the Vout versus Ta curve
using the following formula.
