A digital-to analog-converter (DAC) has a MSB resistor ladder with a plurality of series connected resistors, wherein the MSB resistor ladder is coupled between a first and second reference potential, a LSB resistor ladder with a plurality of series connected resistors, and a plurality of switching units for connecting one of the series connected resistors of the MSB resistor ladder with the LSB resistor ladder, wherein each switching unit has a first switch for connecting a first terminal of an associated MSB resistor with a first terminal of the LSB resistor ladder and a second switch for connecting a second terminal of the associated MSB resistor with a second terminal of the LSB resistor ladder and wherein each switch is configured form a resistor of similar value of the resistors of the LSB resistor ladder when switched on.
