PROBLEM TO BE SOLVED: To provide a sensor output correction circuit in which sensor output can be corrected with high accuracy.SOLUTION: A sensor output correction circuit is provided for correcting sensor output supplied from a sensor 21 and comprises an A/D converter 3 to which either an input voltage corresponding to the sensor output or a predetermined reference voltage is inputted selectively, and an arithmetic circuit 9 which uses an output result of the A/D converter 3 in the case where the reference voltage is inputted, to correct output data of the A/D converter 3 in the case where the input voltage is inputted. The arithmetic circuit 9 includes a multiplier/adder 7 which is used for correcting the output data, and a divider 8 which uses a non-restoring method. |
