The figure is a temperature test circuit with thermistors. In the circuit, thermistors are used as the temperature sensor RT, the testing temperature is divided into 9 levels. By using comparators of Al一A8, the output high-low LEV represents the tested temperature. The relationships between LEV output by U.I-U.8 and temperature are listed in the table.
