Abstract

PURPOSE: To simplify an A-D conversion input processing circuit by jointly using an interface circuit for a plurality of detectors.
CONSTITUTION: The resistance of thermistors 1W4 changes depending on the ambient temperature. If selection signals SEL1, SEL2 produced by a controller are encoded to measure the temperature of the thermistor 1, the output of a decoder 12 turns on a transistor 14 and the output of an interface circuit 5 becomes a voltage corresponding to the resistance of the thermistor 1. When an A-D converter 10 receives a start signal, the converter changes its input analogue voltage into a digital voltage. Similar operation is performed to measure the temperature of the other thermistors 2W4.
