RE: Yes. Dynamic Element Mathcing (DEM)

Not the older Burr-Brown full resolution DACs, such the PCM63 or PCM1702/1704. However, the newer Burr-Brown/T.I. sigma-delta based PCM179x series DACs utilize a type of DEM called data-weighted-averaging (DWA) to convert the quantizer element inaccuracy (which otherwise produce distortion) in to random noise. See the below youtube video for an explanantion on the differences.
