A charge coupled digital to analog converter includes a charge divider coupled to a reference charge generator for producing a plurality of predetermined reference charge portions. The charge portions are applied to a plurality of charge gates, each having outputs and each being coupled to a conditional clock generator for selectively sinking or transferring the charge portion it receives in response to a digital signal to be converted. A charge summer is coupled to receive transferred charge portions from the plurality of charge gates for summing the charge portions received and applying the summed charge to a charge-to-voltage converter which produces an analog voltage corresponding to the applied digital signal.
