Abstract:
A circuit device includes an A/D conversion circuit that performs A/D conversion on a temperature detection voltage from a temperature sensor so as to output temperature detection data, and a digital signal processing circuit that performs a temperature compensation process on the basis of the temperature detection data, in which the A/D conversion circuit operates in a first mode, and switches to a second mode in a case where a predetermined condition is established.
