Abstract
A circuit device including: a detection circuit () that performs A/D conversion of a first detection voltage (VD) that is detected by using a thermopile (), and outputs a first detection value (DT) that is a digital value, and performs A/D conversion of a second detection voltage (VD) that is detected by using a thermistor (), and outputs a second detection value (DT) that is a digital value; and a control unit () that obtains a self-temperature by using the second detection value (DT), obtains a second electromotive voltage that corresponds to the self-temperature by using the self-temperature, obtains a first electromotive voltage that corresponds to an object's temperature by using the first detection value (DT) and the second electromotive voltage, and obtains the object's temperature by using the first electromotive voltage.
