Abstract
A circuit apparatus includes a voltage output circuit that outputs a first output voltage when a first current of first temperature characteristics flows in a resistance element, and a second output voltage when a second current of second temperature characteristics different from the first temperature characteristics flows in the resistance element, an A/D conversion circuit that outputs a first digital value by performing A/D conversion on the first output voltage, and outputs a second digital value by performing A/D conversion on the second output voltage, and a processing unit that obtains temperature data by digital calculation processing of the first digital value and the second digital value.
