<p>There is disclosed an integrated circuit that includes a digital-to-analog converter (e.g., 10) having a resistor string (e.g., 14) driven by a current source (e.g., 12). The resistor string is coupled to the current source. Intermediate taps (e.g., T1 through Tn+1) are defined at the resistor junctions as well the resistor-current source junctions. Switching transistors (e.g., M1 through Mn+1) are coupled between an output node and a respective intermediate tap. A selection circuit (e.g., 2) 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 (e.g., 16). <IMAGE></p> |
