Method and apparatus for combining outputs of multiple DACs for increased bit resolution. A method for providing an increased bit resolution to a data converter operable to convert digital information to analog values. A first current Digital-to-Analog (IDAC) converter is controlled to provide current to a first output node, the first IDAC having a first current step size associated with the Least Significant Bit (LSB) thereof. A second IDAC is controlled to provide current to the first output node, the second IDAC having a second current step size associated with the LSB thereof that is smaller than the first current step size. The combination of the first and second IDACs increases the bit resolution of the first IDAC when driving the first output node with the second IDAC.
