Evaluation and Demonstration Boards and Kits provide the ideal way to evaluate and demonstrate system designs. The EVAL6472H is one of these products. It is a multi-channel digital isolator evaluation board, designed by Analog Devices, Inc., to evaluate the benefits of reducing radiated emissions in low-voltage digital circuits.

The EVAL6472H is an adapter board for the ADuM7000 series of digital isolators and provides access to two separate voltage rails that can be placed at different voltage levels. This allows users to test multiple scenarios with different input and output voltages. The adapter board supports up to eight channels of digital isolation, making it suitable for use in medium and large digital system designs.

Functionally, the EVAL6472H can operate from either 3.3 V or 5 V power supplies. This feature allows the board to be used in a variety of applications. For example, in applications where both the user\'s system and the EVAL6472H are powered from a single 3.3 V supply, the user\'s system can pass data from the 3.3 V side of the digital isolator to the 5 V side, using isolated channels on the EVAL6472H. Another example is in applications where the system\'s power supply is different than the EVAL6472H\'s power supply, the user can use the EVAL6472H to bridge the power supply mismatch. The EVAL6472H is also equipped with LEDs to monitor each channel\'s voltage and current.

The capabilities of the EVAL6472H make it suitable for a wide range of applications. It is an excellent choice for evaluating and demonstrating designs that require digital isolation, such as motor control systems, power generators, and power converters. Additionally, the onboard LEDs allow a user to easily verify the operation of the digital lines, making it suitable for systems that require real-time user feedback, such as industrial automation, instrumentation, and process control. The EVAL6472H also provides the necessary circuit protection for both the system-under-test and the control system, safeguarding both against potential faults.

The EVAL6472H utilizes an advanced digital isolator chip set and provides customers with a high level of isolation, making it a valuable tool for customers to evaluate the benefits of digital isolation. The isolator chips are implemented in an 8-channel circuit, allowing data to pass between different voltage rails and providing isolation of up to 8kV. Additionally, the EVAL6472H is designed for low-voltage and low-power applications, making it suitable for applications that may not be able to tolerate high voltage or power levels.

The EVAL6472H evaluation board is designed to provide reliable data communication between two circuit nodes, while reducing radiated emissions. Its flexibility and wide range of applications make it an ideal choice for customers looking to reduce system noise, reduce cost, and improve system performance. Additionally, the onboard LEDs allow customers to verify data transfer and performance, while onboard protection allows for sufficient circuit safety.
