Abstract:
In an A/D converter, a first analog signal which is input to an input terminal in a state in which the input terminal and a reference voltage line are connected via a first capacitor is converted into digital data when a reference signal is supplied to the reference signal line in a state in which the reference signal line and a first input terminal of a comparator are connected via the first capacitor. A second analog signal which is input to the input terminal in a state in which the input terminal and the reference voltage line are connected via a second capacitor is converted into digital data when the reference signal is supplied to the reference signal line in a state in which the reference signal line and the first input terminal of the comparator are connected via the second capacitor.
