<p>Specifically provided is a magnetic detection device which has a compact circuit configuration compared with conventional magnetic detection devices and has excellent detection accuracy. A bridge circuit is configured by providing a plurality of magnetic detection elements wherein the electrical characteristics change with respect to external magnetic fields. Two output sections are provided at the middle of each of the series circuits of the bridge circuit. Resistance sections (25, 26) are respectively connected to between a first output section (a1), which is provided on the side of an input terminal (Vdd), and a second output section (a2), which is provided on the side of a ground terminal (GND), in one series circuit, and between a third output section (a3), which is provided on the side of the input terminal (Vdd), and a fourth output section (a4), which is provided on the side of the ground terminal (GND), in the other series circuit. The first output section and the fourth output section are connected to a first comparator (30), and the second output section and the third output section are connected to a second comparator (31).</p> |
