Abstract:
This D/A converter includes a plurality of D/A converter elements, each comprising current sources configured to supply output currents to output nodes, and first switches configured to control the output currents. The output nodes are connected to a capacitor section having second switches and a capacitive load. The D/A converter further includes a switch control circuit configured to control the first switches responsive to digital signals, and also control the second switches in accordance with the control of the ON/OFF state of the first switches.
