Provided is an A/D converter (130, 300, 500, 700) including an input terminal (IN), a reference signal line (171) for supplying a reference signal which changes temporally, a comparator (CMP), a correction capacitor (Coff) connected to an inverting input terminal of the comparator; and an output circuit (330) which outputs digital data corresponding to an analog signal input to the input terminal. In a first state in which a total voltage of a first analog signal and an offset voltage of the comparator is held in the correction capacitor, a second analog signal input to the input terminal is supplied to a non-inverting input terminal of the comparator, and the second analog signal or the total voltage is changed using the reference signal, thereby outputting, from the output circuit, digital data. |
