TWI658283B

A magnetic sensor circuit which does not output peak-shaped voltage errors to a signal processing circuit is provided. The magnetic sensor circuit is characterized by comprising a plurality of Hall elements driven by a first switch circuit, signals are output to the signal processing circuit via a second switch circuit controlled by a second control circuit so as to control the first switch circuit, all output signals of the plurality of Hall elements are different in time for generating peaks, and the second switch circuit chooses not to output signals when peaks are not generated.
