2.2 Hardware Setup
This section provides the overall system setup for the EVM. The hardware setup contains the TI Launchpad
(TIVA Connected Launchpad™), BOOSTXL-DAC-PORT, and DAC53204EVM. A PC runs the software that
provides an interface to the DAC53204EVM 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
level translators used on the BOOSTXL-DAC-PORT and DAC53204EVM 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.
