3 Detailed Description
3.1 Hardware Description
The following sections provide detailed information on the EVM hardware and jumper configuration
settings.
3.1.1 Theory of Operation for the BOOSTXL-DAC-PORT
The BOOSTXL-DAC-PORT is a generic evaluation platform for catalog DACs that provides various
options for power supply, reference, communication interfaces, and GPIO for a DAC EVM. The DAC EVM
interfaces with a predefined set of signals common to a precision DAC. The block diagram of this board is
shown in
Figure 7 .
