Abstract

Representative implementations of devices and techniques provide digital-to-analog conversion of signals while minimizing switching related errors. Digital to analog converter (DAC) cells may be arranged to include one or more operating states in addition to binary output states, and may employ a switching technique to “dump” the DAC cell between binary outputs. Further, an array of DAC cells may include a partial set of redundant DAC cells for implementation of the switching technique.
