Abstract
A driving circuit that drives a Hall element for use in a brushless DC motor includes a reference-voltage generator that generates a reference voltage, an operational amplifier to which the reference voltage is input, and a resistance. One of input terminals and GND terminals of all of one or more Hall elements included in the driving circuit are connected to an output end of the operational amplifier. Predetermined potential is applied to the other of the input terminals and the GND terminals of all of the one or more Hall elements. The one or more Hall elements and the resistance are connected in series between a first power supply voltage and ground potential.
