What is the resolution of a digital-to-analog converter (DAC)?
It is the comparison between the actual output of the converter and its expected output.
It is the deviation between the ideal straight-line output and the actual output of the converter.
It is the smallest analog output change that can occur as a result of an increment in the digital input.
It is its ability to resolve between forward and reverse steps when sequenced over its entire range.
