Evaluation and Demonstration Boards and Kits

The EVAL-ADUM5411EBZ is an evaluation and demonstration board specifically designed to provide an easy-to-use platform to evaluate the performance of the ADuM5411 isolated DC-DC digital isolator. The board includes hardware and board layout features optimized for responsive evaluation of the ADuM5411 device. This board can be used to develop a variety of isolated applications in the area of communications, medical, industrial, and automotive.

Application Field

The EVAL-ADUM5411EBZ is designed to provide a reliable platform for the evaluation of ADuM5411 digital isolator. Specifically, it can be used to evaluate common mode noise rejection ratios, speed of data transfer, and distance between the isolated devices. The board enables users to rapidly and easily evaluate the ADuM5411 performance in various isolated applications where the ADuM5411 may be used. Such applications include powering and communications in medical devices, industrial equipment, LED lighting, automotive systems, and communications equipment.

Working Principle

The working principle of the EVAL-ADUM5411EBZ is to provide isolated power to the isolated system, while saving board size and cost. The board consists of two boards: the Isolation Side Board and the Power Side Board. The Isolation Side Board acts as a barrier to prevent the passage of electrical signals between the two boards, but allows the transmission of data signals using the ADuM5411 isolator. The Power Side Board is responsible for providing power to the isolated system, while the Isolation Side Board provides the electrical and signal isolation. The two boards are electrically isolated from each other by a transformer, providing the ability to use separate power and ground planes on the boards.

In operation, the Isolation Side Board provides the signal isolation between the two boards using the ADuM5411 isolator. The ADuM5411 isolator provides a signal speed of up to 3.125 Mbps and a common mode noise rejection ratio of up to 50 dB at 100 kHz. The Isolation Side Board also includes a comparator with a reference level of 5 V, allowing for the detection of noise level differences.

The Power Side Board is responsible for providing the power to the isolated system, as well as providing a common ground between the two boards. The board includes a transformer, which is used to provide the power isolation for the isolated system. The board includes a DC-DC converter to supply the isolated power to the Isolation Side Board, while the isolated ground is routed to the system ground terminal. The board also contains a DC-DC buck converter to supply power to the ADuM5411 isolator.

Conclusion

In conclusion, the EVAL-ADUM5411EBZ evaluation and demonstration board is an ideal platform for evaluating the performance of the ADuM5411 isolated DC-DC digital isolator. The board enables users to evaluate the ADuM5411 performance in various isolated applications such as powering and communications in medical devices, industrial equipment, LED lighting, automotive systems, and communications equipment. The board consists of two boards: the Isolation Side Board and the Power Side Board, which are electrically isolated from each other by a transformer. The Isolation Side Board is used to provide signal isolation between the two boards using the ADuM5411 isolator, while the Power Side Board is responsible for providing power to the isolated system.
