1. Digital to analog conversion circuitry comprising a path for processing data in a 1-bit format comprising:

  • a first portion of a finite impulse response filter comprising a preselected number of delay elements for receiving a stream of data in the 1-bit format and outputting a plurality of signals in response; and

    a switched capacitor digital to analog converter forming a second portion of the finite impulse response filter having a plurality of elements each receiving a one of the plurality of signals selected as a function of a set of filter coefficients, said converter summing the plurality of signals and outputting an analog data stream.
