摘要： The present invention relates to a multi-bit digital to analogue converter (DAC) and to a delta-sigma analogue to digital converter employing such a DAC. The DAC has a multi-bit input, a plurality of elements for processing an input signal received at the input and a selector for selecting, based on the input signal, one or more of the DAC elements to process the signal. The DAC has control means for controlling the selector such that if the input to the DAC is below a predetermined level for a predetermined period of time the selector is operative to select only a single one of the DAC elements to process the input signal. Also disclosed is a delta-sigma analogue to digital converter (ADC) employing such a DAC.
