Magnetic detection device including circuit capable of switching over output mode of N pole and S pole between non-separated one output and separated two outputs

摘要

A magnetic detection device includes a mode switching section capable of switching over a 1-output mode in which a (+) magnetic-field detected signal and a (−) magnetic-field detected signal are both outputted from a 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 a second external output terminal. The provision of the mode switching section in an integrated circuit makes it possible to perform mode selection, in particular to realize the mode selection with a simple circuit configuration resulting in a reduction of the production cost.
