A D/A converter. The D/A converter comprises a R-2R ladder network and a correction circuit. The R-2R ladder network receives first and second reference voltage terminals and generates an analog voltage at an output terminal in response to a digital input code. The correction circuit, coupled between the first and second reference voltage terminals via a first switch and a second switch respectively, comprises a plurality of R resistors wherein a terminal of one of the R resistors thereof is coupled to the output terminal via a third switch, and the first, second and third switches are turned on in response to the input digital code.
