Abstract
A successive approximation type AD converter includes a charge redistribution type DA conversion circuit, a comparator, and a control circuit. The charge redistribution type DA conversion circuit is configured such that each of k unit elements connects a switch and a unit capacitance in series and includes a unit capacitor array that is connected to a common output line in parallel and a selector that selects one voltage supplied to one input terminal, through m voltage supply lines, among at least three input terminals of switches included in j unit elements which are the targets for dynamic element matching (DEM) in k unit elements based on the DEM.
