Patent ID: 7402998

Claim:
A magnetic detection device comprising: a sensor section having electrical characteristics changed depending on magnetic-field intensity changes of an external magnetic field in a positive (+) direction, and an external magnetic field in a negative (−) direction opposed to the (+) direction, and an integrated circuit connected to said sensor section, the integrated circuit being operable to produce and output a positive (+) magnetic-field detected signal and a negative (−) magnetic-field detected signal in accordance with the electrical changes, said integrated circuit comprising: a first external output terminal and a second external output terminal; and a mode switching section capable of switching over a 1-output mode in which the (+) magnetic-field detected signal and the (−) magnetic-field detected signal are both outputted from the first external output terminal, and a 2-output mode in which the (+) magnetic-field detected signal and the (−) magnetic-field detected signal are outputted respectively from the first external output terminal and the second external output terminal.
