A digital-to-analog converter includes a plurality of current sources, a differential amplifier, and a plurality of switching modules. The plurality of switching modules is operably coupled to the plurality of current sources and the digital amplifier module provides the analog output for the digital-to-analog converter. Each of the plurality of switching modules has a corresponding current source of the plurality of current sources, where a 1<st >set of the plurality of switching modules couples the corresponding current sources to the differential amplifier module in a 1<st >manner based on a digital input value and a 2<nd >set of the plurality of switching modules couples the corresponding current sources to the differential amplifier in a 2<nd >manner based on the digital input values such that, over time, errors introduced by the coupling in the 1<st >manner substantially compensates for errors introduced by the coupling in the 2<nd >manner.
