An improved digital-to-analog converter (DAC) is disclosed herein. Multiple switches are used to connect a single current source to one side of a differential output when multiple bits representing the same digital value are received during successive clock cycles. By employing non-overlapping phase clocks, each of the switches can be opened and closed during an appropriate portion of a clock cycle. Using the switch arrangement disclosed herein to connect the current sources to the differential output provides the advantages of increased accuracy, low current draw, and a reduced necessity for current matching multiple current sources.
