Abstract
A temperature sensor has a series circuit of resistors, a gain control switch connected in parallel with one of the resistors of the series circuit, and a reference voltage control switch connected in parallel with a middle resistor of resistors of a reference voltage generation section. The reference voltage and the gain of an operational amplifier are variable so as to change the resolution of the output signal and/or a detected temperature range of the sensor.
