Abstract
A magnetic sensor device for generating a logic output in accordance with a magnetic field intensity applied to a magnetoelectric conversion element includes: a comparator for inputting amplified output signals of the magnetoelectric conversion element, and outputting a comparison result; and a logic circuit for performing arithmetic processing on an output signal of the comparator. Only when the logic output is changed by a change in the magnetic field intensity, the logic circuit performs successive matching determination of logic outputs a plurality of times. Thus, the variation in determination for detection or canceling of a magnetic field intensity, which is caused by noise generated from respective constituent elements included in the magnetic sensor device and external noise, may be reduced while suppressing electric power consumption.
