Hardware Setup
This section provides the overall system setup for the EVM. The hardware setup contains the Analog EVM
Controller (MSP-EXP432E401Y Launchpad), BOOSTXL-DAC-PORT, and DAC53608EVM. A PC runs
software that provides an interface to the DAC53608EVM through the Analog EVM Controller. The Analog
EVM Controller generates 5V power that can be used as VDD for the DAC. It also generates a 3.3V
power that can be used for I2C pull-ups. The IO ports of Analog EVM Controller and level translators used
on the BOOSTXL-DAC-PORT and DAC53608EVM can withstand a maximum of 3.6V IO levels. The
Analog EVM Controller also generates digital signals used to communicate with the EVM board. The
BOOSTXL-DAC-PORT is a generic platform used for catalog DACs. It provides a predefined interface to
connect a DAC evaluation module. It 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.
