Abstract
A plurality of segment groups constituting a D/A converter, and decoders for decoding digital signals and selecting segments constituting the segment groups are arranged on a semiconductor chip. The segments constituting the plurality of segment groups are mingled and two-dimensionally arranged. The positions of the centers of gravity of the respective segment groups are substantially matched with the center of the arranged segments.
