Abstract
A sensor output correction circuit includes an analog-to-digital converter configured to receive an input voltage corresponding to a sensor output of a sensor and a reference voltage that are selectively input to the analog-to-digital converter; and an arithmetic unit configured to correct output data, which is output from the analog-to-digital converter when the input voltage is input to the analog-to-digital converter, based on an output value that is output from the analog-to-digital converter when the reference voltage is input to the analog-to-digital converter. The arithmetic unit includes a multiply adder and a non-restoring divider.
