An apparatus and method for reducing distortion from an output of a digital-to-analog converter (DAC). In one implementation, the distortion being reduced is third order harmonic distortion caused by charge transfer effects and instantaneous output impedance drop during switching. Each of the embodiments includes a module adapted to generate a distortion correction signal being a function of the input digital signal, the full scale code of the DAC, the load resistance, the conversion rate of the DAC, and a proportionality constant. In another implementation, the distortion being reduced is higher order harmonic distortion caused by timing skew between a main DAC and a least significant bit (LSB) DAC. Each of the embodiments includes a module adapted to generate a distortion correction signal being a function of the input digital signal, the number of levels covered by the LSB DAC, the conversion rate of the DAC, and the timing skew.
