Methods and systems are provided for using localized dynamic element matching (DEM) and/or dynamic noise scaling (DNS) in digital-to-analog converters (DACs). Adaptive (localized) DEM may be applied in a DAC, by selecting one or more of a plurality DAC elements in the DAC, forcing the selected one or more of the plurality of DAC elements not to switch during digital-to-analog conversions, and scrambling remaining one or more of plurality of DAC elements when generating an output of the DAC. The adaptive DEM may be applied when the DAC input is backed off from full-scale. DNS may be applied in a DAC, by adaptively selecting one or more of a plurality DAC elements in the DAC and switching off the selected one or more of the plurality DAC elements such that the selected one or more of the plurality DAC elements do not contribute to generating an output of the DAC.
