摘要

A physical quantity sensor includes a physical quantity sensor element and an IC connected to the physical quantity sensor element. The IC includes an analog power supply circuit that is switched to enable or disable, a signal processing unit to which a voltage is supplied from the analog power supply circuit and which processes a signal from the physical quantity sensor element, and a control circuit that sets the analog power supply circuit to enable within a processing period based on an external trigger and makes the signal processing unit process a physical quantity signal from the physical quantity sensor element intermittently for every processing period.
