Abstract
An A/D converter has a successive approximation register having a plurality of A/D registers each corresponding to one of A/D inputs. A capacitor in a comparator is charged by a voltage determined based on a value held in an A/D register corresponding to an A/D input to be A/D converted before starting A/D conversion of the A/D input, thereby reducing noise generated at the time of selecting A/D inputs to enhance A/D conversion accuracy.
