Sigma-delta techniques extend DAC resolution
by Tim Wescott
Motion control systems often require digital-to-analog converters with high resolution but not high accuracy. Because high-accuracy DACs are expensive and consume valuable board space, a good solution is to extend your DAC's resolution in software. This article presents such a technique.
