Abstract: A digital-to-analog converter (DAC) and a method for operating the DAC are disclosed. The DAC receives, over a first channel, a control signal that is transmitted in accordance with a binary protocol. The DAC also receives, over a second channel different than the first channel, data that is transmitted in accordance with a multilevel communication protocol that is different than the binary protocol. The DAC determines a plurality of first and second voltages based on the received data and identifies, based on the control signal, a time when data transmission or reception is switched between first and second antennas. In response to identifying, based on the control signal, the time when data transmission or reception is switched, the DAC outputs the determined plurality of first voltages to a first antenna tuning circuit or the determined plurality of second voltages to a second antenna tuning circuit.
