In an example, there is disclosed a multi-stage Digital to Analog Convertor, including: a first stage having a first set of circuit components, a second stage having a second set of circuit components and a third stage having a third set of circuit components, the third stage providing a load within first and second individual switchable impedance paths; wherein the DAC is operable in each of a first mode, a second mode and a third mode of operation, wherein in a first mode the first stage is switchably coupled to the second stage independently of the third stage; in a second mode, the load is coupled and presented to a first part of the second stage of circuit components and in a third mode the load is coupled and presented to a second, different, part of the second stage of circuit components. A corresponding system and method is also disclosed.
