ABSTRACT:
A D-to-A converter of the type having a number of current sources each connected to a pair of switches operable by binary control pulses for directing the source current either to the output line or to ground. Power to operate the DAC is reduced by special control circuitry which opens both switches of any given switch pair whenever two successive control pulses call for the output-line switch to be open.
