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 and AFEs that provides various 
options for power supply, reference, communication interfaces, and GPIO for a DAC or AFE EVM. The 
AFE539A4 EVM interfaces with a predefined set of pins common to a precision DAC or AFE. The block diagram 
of this board is shown in
