ABSTRACT:
A physical amount detecting apparatus, preferably, an acceleration sensor, includes a sensor element, an A/D converter, a control unit and an activation unit. The sensor element is activated by a supply voltage and outputs an electric signal in accordance with a predetermined physical amount. The A/D converter digitizes an analog electric signal and outputs digital data. The control unit calculates a control amount in order to control the sensor element, as the electric signal is set to a predetermined output, based on the digital data, and generates a control signal in accordance with the control amount. The activation unit activates the sensor element in accordance with the control signal. As a result, the control unit outputs a detecting signal indicating a physical amount in accordance with the control amount or the control signal.
