1. A method of efficient shuffling in a digital-to-analog converter circuit comprising a plurality of single-bit converters having a common nominal gain and a common nominal offset, the method comprising:
receiving a digital input signal having a value;
determining a number of the plurality of single-bit converters that, when activated at the digital-to-analog converter circuit, cause an output of the digital-to-analog converter circuit to indicate the value of the digital input signal;
determining, based on the value of the digital input signal and the number, a minimum set of output configurations for causing the output of the digital-to-analog converter circuit to indicate the value of the digital input signal while maintaining a linear relationship between the value of the digital input signal and the output of the digital-to-analog converter circuit;
selecting an output configuration from the minimum set of output configurations; and
transmitting the selected output configuration to the plurality of converters.
