AN929: Temperature Measurement Circuits for Embedded Applications. Discrete-component circuits for both continuous temperature measurement and over- temperature alarm indication have traditionally used a thermal-resistor (thermistor) for a sensor element (Figure 1). The most commonly used thermistor is a negative- temperature-coefficient (NTC) thermistor as This sensor is called a thermistor. A thermistor exhibits resistance that is far more sensitive to temperature than that of other types of resistors.For this reason, for most low-cost temperature measurement, NTC thermistors are preferred.This will be our interface circuit to our thermistor.
