1. A circuit, comprisinga digital-to-analog converter (DAC) configured to receive a digital code input, wherein the DAC comprises:
- a first output terminal configured to provide a current output based on the digital code input;
a second output terminal configured to provide a voltage output based on the digital code input; and
a mode-select terminal configured to select one of a plurality of modes for the DAC,wherein the plurality of modes comprise a current source mode and a current sink mode, and wherein the DAC is configured to provide a current source for the current output when the current source mode is selected and provide a current sink for the current output when the current source mode is selected.
