Current steering DAC, a video adapter including a current steering DAC, and a video circuit including a current steering DAC

A current steering Digital-to-Analog Converter (DAC), a video adapter including a current steering DAC, and a video circuit including a current steering DAC are described. In one embodiment, a current steering DAC includes multiple DAC unit cells that are connected in parallel with each other. Each of the DAC unit cells includes three output switches connected to a current source. The three output switches are configured to form two differential pairs of switches that are placed in parallel with each other and share a negative output switch of the three output switches. The current steering DAC also includes at least one switch control circuit configured to receive digital input data and to control the three output switches of each of the DAC unit cells to generate differential analog output data based on the digital input data and a current from the current source. Other embodiments are also described.
