ABSTRACT:
There is disclosed an integrated circuit that includes a digital-to-analog converter having a resistor string driven by a current source. The resistor string is coupled to the current source. Intermediate taps are defined at the resistor junctions as well the resistor-current source junctions. Switching transistors are coupled between an output node and a respective intermediate tap. A selection circuit is coupled to a terminal of each switching transistor for selectively switching the transistors to a predetermined state to electrically couple the associated intermediate tap to the output node.
