Abstract
An integrated circuit includes a Wheatstone bridge and a bias voltage circuit. The Wheatstone bridge includes a first resistor connected between a first node on a high potential side at which a predetermined voltage is generated and a second node, a second resistor connected between the second node and a third node on a low potential side, a third resistor connected between the first node and a fourth node, and a fourth resistor connected between the fourth node and the third node. The bias voltage circuit includes a fifth resistor having a first end connected to the third node and a second end, and a first operational amplifier circuit having an inverting input terminal to which the second end of the fifth resistor is connected, a non-inverting input terminal configured to receive a reference voltage lower than the predetermined voltage, and an output terminal connected to the third node.
