In an analog-to-digital converter, a generating unit executes analog-to-digital conversion of a first input signal and a second input signal based on an analog-to-digital conversion characteristic curve to generate first digital data and second digital data respectively corresponding to the first input signal and the second input signal. The input signal has a first level, and the first level is the sum of an offset level and a level of a target analog signal for analog-to-digital conversion. The second input signal has a second level, and the second level is generated by subtracting the offset level from the level of the target analog signal. In the analog-to-digital converter, an obtaining unit obtains difference digital data between the first digital data and the second digital data to output the obtained difference digital data as digital data of the target analog signal.
