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 TPL1401EVM. A PC runs software that provides an interface to the TPL1401EVM through the Analog EVM Controller.
The Analog EVM Controller generates 5 V of power that can be used as VDD for the DAC. Analog EVM Controller also generates 3.3 V of power that can be used for I2C pull-ups. The IO ports of the Analog EVM Controller and level translators used on the BOOSTXL-DAC-PORT and TPL1401EVM can withstand a maximum of 3.6-V 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 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 setup.
