Abstract
An A/D converter which converts an analog input signal into a digital output signal by performing time-divisional parallel processings on the analog input signal using first and second pipeline type unit A/D converters. The A/D converter sets plural unit A/D converters performing parallel processings according to a system request, such that, when the A/D converter operates with a conversion frequency that is lower than the maximum conversion frequency, the unit A/D converter is halted by a control signal, thereby reducing inter-channel errors among the unit A/D converters to improve the precision of the A/D converter.
