Abstract
A multiple impedance string, multiple output digital-to-analog converter (DAC) circuit that can include a shared coarse resolution DAC, two first fine resolution DACs to receive outputs of the MSB DAC, and a multiplexer to multiplex outputs of the first and second fine resolution DACs to output terminals. The multiplexer can be configured to interchange coupling of the outputs of the first and second fine resolution DACs using one or more MSBs.
