Temperature Sensor IC
s Overview
The AN6701S is an integrated circuit designed for temperature sensing. Since a temperature characteristic adjusting circuit and buffer amp. in addition to temperature sensor circuit are integrated, the temperature sensing operation with high sensitivity as well as high precision can easily be done by a single external resistor.
