The invention is a circuit that combines a VDAC (Digital to Analog Converter Voltage source) and an IDAC (Digital to Analog Converter Current source) into one circuit. This is done by reusing the largest elements of the IDAC for the VDAC. The circuit is either in the mode of a VDAC or an IDAC. The two circuits have three main elements which are: Opamp, feedback and output stage. The elements which are shared between the two circuits are the Opamp and the output stage.
