A digital-to-analog conversion circuit (DAC) is operable to convert an input digital signal to an output analog signal. The DAC includes a digital signal processing circuit operable to process the input digital signal according to a first transfer function to generate a first processed digital signal and process the digital input signal according to a second transfer function to generate a second processed digital signal. The DAC includes a first unit DAC operable to convert the first processed digital signal to a first intermediate analog signal, and a second unit DAC operable to convert the second processed digital signal to a second intermediate analog signal. The DAC includes switching circuits and a combiner circuit to generate the output analog signal from the intermediate analog signals.
