ABSTRACT:
A D/A conversion circuit for performing D/A conversion at high speeds. The D/A conversion circuit includes a resistor string including a plurality of resistor elements connected between a low-potential power supply and a high-potential power supply. A plurality of first switch groups are connected to the connection nodes between the resistor elements for selectively outputting voltages at the connection nodes. The outputs of the switches of the first switch groups are connected in common to a corresponding one of the nodes. The plurality of nodes are connected to an output terminal of the D/A conversion circuit via a second switch group. Predetermined switches of the first switch groups are connected in parallel to third switches to apply voltages to the nodes.
