Texas Instruments DAC53701EVM, User Manual, Page: 7 / 38

2.2 Hardware Setup
This section provides the overall system setup for the EVM. The hardware setup contains the TI Launchpad
(MSP-EXP432E401Y Launchpad), BOOSTXL-DAC-PORT, and DAC53701EVM. A PC runs the software that
provides an interface to the DAC53701EVM through the TI Launchpad.
The TI Launchpad generates 5 V of power that can be used as VDD for the DAC. The TI Launchpad also
generates 3.3 V of power that can be used for I
2
C pullups. The IO ports of the Analog EVM Controller and level
translators used on the BOOSTXL-DAC-PORT and DAC53701EVM can withstand a maximum of 3.6-V IO
levels. The TI Launchpad also generates digital signals used to communicate with the EVM board.
The BOOSTXL-DAC-PORT is a generic platform used for catalog DACs that provides a predefined interface to
connect a DAC evaluation module. The BOOSTXL-DAC-PORT also provides various options for power supply,
reference, and digital signals. A connector is provided on the BOOSTXL-DAC-PORT for external power supplies.
This platform is designed to host additional boards stacked up on the BOOSTXL-DAC-PORT in order to provide
extended functions.
Figure 2-5 displays the system hardware setup.

2.2.1 Power Configurations and Jumper Settings
The DAC53701EVM provides electrical connections to the device supply pins. The connectors and optional
configurations are shown in
Table 2-1 . The jumper settings on the BOOSTXL-DAC-PORT are crucial to the
proper functioning of the DAC53701EVM. Table 2-2 provides the details of the possible jumper settings on the
BOOSTXL-DAC-PORT.
