PROBLEM TO BE SOLVED: To provide a circuit arrangement, a temperature detector, an electronic device, and a temperature detection method which enable highly accurate temperature detection according to the characteristics of a thermopile.SOLUTION: The circuit arrangement includes a detection circuit 10 and a controller 50. The detection circuit 10 performs A/D conversion on a first detected voltage VD1 detected with a thermopile 2 and outputs a first detection value DT1 as a digital value, as well as performs A/D conversion on a second detected voltage VD2 detected with a thermistor 4 and outputs a second detection value DT2 as a digital value. The controller 50 obtains a self temperature from the second detection value DT2, obtains a second starting voltage value for the self temperature from the self temperature, obtains a first starting voltage value for an object temperature from the first detection value DT1 and the second starting voltage value, and obtains the object temperature from the first starting voltage value. |
