Abstract
In an embodiment, a digital-to-analog converter (DAC) includes inputs for receiving first and second signals encoded as a digital signal pair including overlapping low value portions that are substantially equal in duration to overlapping high value portions, within a frame. The DAC further includes an output terminal for providing an analog signal and includes first and second switches responsive to the first and second signals alter a level of the analog signal based on values of the first and second signals to provide a mismatch-immune DAC functionality. In one instance, the switches couple current sources to a common node. In another instance, the switches configure a resistive network to alter a resistance at an input to an amplifier.
