Abstract
The invention relates to an N-bit digital-to-analogue converter (DAC) system, comprising—a DAC unit comprising an N-bit master DAC and a slave DAC, yielding a master DAC unit output signal and a slave DAC unit output signal, respectively, said N-bit master DAC having an output step size,—an adder unit combining the master DAC unit output signal and the slave DAC unit output signal, and—a means for storing correction values for at least the master DAC, said correction values being used by the slave DAC, whereby the DAC system is arranged for master DAC output corrections with a size in absolute value higher than half of the output step size.
