Abstract
A analog-digital conversion device is provided with a comparison unit, a holding unit, a bidirectional conveying unit, and a control unit. The comparison unit compares an input signal with a reference signal. The holding unit holds a digital signal corresponding to the reference signal in the timing in which a result of the comparison has changed. The bidirectional conveying unit inputs a digital signal into the holding unit to cause the holding unit to hold the digital signal, and reads the held digital signal as a result of analog-digital conversion for the input signal. The control unit controls internal resistance of the bidirectional conveying unit to be set at a value that differs between when the holding unit is caused to hold the digital signal, and when the held digital signal is read from the holding unit.
