Digital-to-analog converters (DACs) are indispensable components of a wide range of electronic applications requiring signals to be converted from digital to analog. In particular, Field Programmable Gate Arrays (FPGAs), which represent digital, integrated circuit logic, require DACs for certain functions. Evaluating the performance of DACs is made easier thanks to the DEM-DAI1772 evaluation board. This article will explain the application field and working principle of this evaluation board.

The DEM-DAI1772 evaluation board is a very useful device for designers and engineers who are evaluating the performance of digital-analog converters (DACs). This evaluation board helps in testing the performance of the device, accuracy of the results, and the interface performance. The DEM-DAI1772 is capable of evaluating various types of DACs, including those utilized in FPGAs and general-purpose ADC/DAC applications. Furthermore, the board is equipped with multiple user interfaces, including a power supply connector, USB, and serial interfaces.

From a technical standpoint, the DEM-DAI1772 is built with an ADCs/DACs loopback and a selectable MUX board. A MUX board is used to connect the ADCs (analog-to-digital converters) and DACs with the evaluation board. Additionally, the components are fully sealed and protected from EMI or RFI interference. This is particularly important when evaluating DACs which are used in communication systems.

The board is easy to install, configure, and operate. Upon power up, the board automatically detects and configures the DACs connected to it, allowing it to quickly determine the performance of the DACs. After selection of the desired operating mode, the user can configure the evaluation board using the PC software. At this stage, various settings can be changed including digital frequency, analog frequency, and gain. For each set of parameters, multiple evaluations are available, such as sweep, tests, distortion spectrum, actual SNR, and oversampling.

To sum up, the DEM-DAI1772 evaluation board is an invaluable tool when evaluating the performance of DACs. Its ability to connect to multiple types of DACs is especially beneficial, as it allows evaluation of different types of devices at once. Furthermore, its user-friendly graphical user interface and automated testing procedures make the task of testing the performance of DACs quick and easy.
