CIRCUIT DEVICE, PHYSICAL-QUANTITY DETECTING APPARATUS, ELECTRONIC APPARATUS, AND MOVING OBJECT

摘要

A circuit device includes a differential input-to-single-ended output first amplifier, to an inversion input terminal of which, of first and second signals forming differential signals, the first signal is input and to a non-inversion input terminal of which the second signal is input, a differential input-to-single-ended output second amplifier, to a non-inversion input terminal of which the first signal is input and to an inversion input terminal of which the second signal is input, and a failure detection circuit that performs failure detection on the basis of an output signal of the first amplifier and an output signal of the second amplifier.
