1. A stimulator device system, comprising:
an electrode node configured to be coupled to an electrode to provide stimulation pulses to a patient's tissue;
a digital-to-analog converter (DAC) configured to receive an input specifying a prescribed amplitude and to produce a first current with a first amplitude at a first node, wherein the first amplitude is scaled in accordance with the prescribed amplitude; and
a plurality of first branches each configured when selected to produce a first branch current, wherein each first branch current comprises a scaled version of the first current, wherein each of the first branches terminates at a second node coupled to the electrode node,
wherein a first output current is provided at the electrode node comprising a sum of the first branch currents of the selected first branches.
