Abstract
A digital to analog converter includes a network of impedance components having a plurality of nodes having associated voltages. A tap is coupled to one or more associated one of the plurality of nodes to source or sink electrical current relative to the associated node(s). A switching system is operative to couple a selected one of the nodes to an output according to a digital input word and thereby provide an analog voltage corresponding to the digital input.
