Abstract
A multiple output, multiple impedance string digital-to-analog converter (DAC) circuit can provide a first output having a first resolution in response to a first digital input signal and a second output having a second resolution in response to a second digital input signal. A main impedance string and a secondary impedance string can be coupled using switching networks to provide a first DAC output. By coupling additional switches to the main impedance string and by sharing the main impedance string, a second DAC output can be realized.
