n Overview
The AN6701S is an integrated circuit designed for tempera-
ture sensing. Since a temperature characteristic adjusting cir-
cuit and buffer amp. in addition to temperature sensor circuit
are integrated, the temperature sensing operation with high sen-
sitivity as well as high precision can easily be done by a single
external resistor.
n Features
• High sensitivity (100mV/˚C)
• Excellent linearity (non linearity.±0.5%)
• Easy calibration with an external resistor
• High precision (±1˚C) with calibration
