发明名称 ELECTRONIC CIRCUIT, INTEGRATED CIRCUIT, AND MAGNETISM DETECTION DEVICE AND ELECTRONIC APPARATUS LOADED WITH THE SAME
摘要 <P>PROBLEM TO BE SOLVED: To provide a magnetism detecting electronic circuit capable of maintaining or improving magnetism detection accuracy without restricting a shape of a magnet or the like to be a detection object and increasing manufacturing cost. <P>SOLUTION: A magnetism detection device 100 includes a magnetism detection circuit 110 and a processing circuit 150. The magnetism detection circuit 110 includes: a magnetism detection section 120 configured by arraying at least three detection blocks each having at least one magnetism detection element and constituted so as to set a distance between first and second detection blocks as a distance suited to an object to be detected by selecting the first and second detection blocks out of the at least three detection blocks in accordance with the object to be detected; a control section 140 for selecting the first and second detection blocks based on setting from the external; and a switching section 130 controlled by the control section 140 to connect the selected detection blocks to the processing circuit 150. <P>COPYRIGHT: (C)2012,JPO&INPIT
