Abstract
An analog-to-digital conversion device includes: an analog-to-digital converter that receives an analog voltage and converts the analog voltage into a digital value to output the converted digital value; and an offset correction unit that arithmetically operates an offset correction value based on a first digital value and a second digital value, the first digital value being to be output from the analog-to-digital converter by the analog-to-digital converter receiving a first analog voltage, the second digital value being to be output from the analog-to-digital converter by the analog-to-digital converter receiving a second analog voltage, the second analog voltage having a voltage value different from that of the first analog voltage, in which after the arithmetic operation of the offset correction value, the analog-to-digital converter outputs a digital value obtained by subtracting the offset correction value from the converted digital value.
