A current digital-to-analog converter (DAC) is disclosed. The current DAC includes a current reference circuit coupled between a voltage source terminal and a voltage node, wherein the current reference circuit includes a feedback node. A switchable resistor network is communicably coupled to the feedback node of the current reference circuit via a first feedback network that is adapted to equalize a first voltage across the switchable resistor network voltage with a second voltage between the feedback node and the voltage node. A current mirror includes an output node communicably coupled to the switchable resistor network via a second feedback network that is adapted to equalize an output current that flows from the output node with an input current that flows into the switchable resistor network.
