Title: High accuracy digital-to-analog converter and transient elimination system thereof

Abstract: A transient-free, high accuracy digital-to-analog converter is disclosed having a resistor network which generates a plurality of equally weighted currents selectively switched to an output bus to provide an output corresponding to the input code, in which a binary input code is decoded into a specialized code such that an incremental increase in the input code causes an additional one of the equally weighted currents to be coupled to the output bus.
