Abstract
A digital-to-analog converter receives a stream of input words and selectively couples a plurality of current sources to produce a DAC output signal. The DAC includes a set of series-connected synchronizing switches and data switches between the current sources and the output lines, and operates the switches such that the current sources are not coupled to the data switches until the data switch transients have ended.
