A low-power reconfigurable voltage-mode digital-to-analog converter (DAC) driver circuit includes a first and a second supply voltage and a number of DAC units. Each DAC unit is coupled to a respective bit of a digital input. The DAC units are configured to maintain a constant output impedance. Each DAC unit includes one or more complementary switch pairs that couple first nodes of one or more respective impedances to one of the first or the second supply voltage, based on the respective bit of the digital input. Second nodes of the one or more respective impedances are coupled to an output node.
