Document Type and Number:
Japanese Patent JP6375685
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a circuit device capable of setting an output temperature range in a variable manner, and further to provide a temperature detector, an electronic apparatus, a temperature detection method and the like.SOLUTION: A circuit device includes: a detection circuit 10 performing A/D conversion for a first detection voltage VD1 detected by using an infrared sensor, outputting a first detection value DT1 of a digital value, performing A/D conversion for a second detection voltage VD2 detected by using a temperature sensor and outputting a second detection value DT1 of a digital value; a control section 50 obtaining a digital value of an object temperature on the basis of the first detection value DT1 and the second detection value DT2; and an output section 90 performing D/A conversion of the digital value of the object temperature and outputting an output voltage corresponding to the object temperature. The output section 90 outputs the output voltage where a temperature range of the object temperature represented by the output voltage is set in a variable manner.
