Abstract
A resistor-based digital to analog converter (DAC) having mux fastpaths, which selectively connect a subset (or an entirety) of voltage divider nodes in a DAC to either a higher level of multiplexor hierarchy, or a DAC output node, effectively bypassing one or more levels of multiplexor devices. In addition, the fastpaths may selectively connect lower levels of multiplexor hierarchy to higher levels of multiplexor hierarchy and/or a DAC output node.
