This section describes the overall system setup for the EVM. A local machine runs the software that provides an interface to the DAC82002EVM through the onboard controller.
The USB connection generates 5 V of power for use as the DAC supply voltage (VDD). The onboard controller generates 3.3 V of power for the input/output (I/O) signals generated by the controller. These I/O signals are level-translated to the VDD voltage of the DAC. Figure 2-3 displays the system hardware setup.
