A mixing DAC includes an analog output network; a current source; a current switching circuit connected between the current source and the analog output network; a switch driver circuit responsive to a digital input at a first rate and a clock signal having a predetermined period for driving the current switching circuit to selectively interconnect the current source and the analog output network; and a waveform generator for driving the current source to produce an output current including a plurality of peaks at a second rate during each clock period to up-convert the response energy of the DAC analog output to approximately the second rate.
