Evaluation and demonstration boards and kits are tools used to understand the functional properties and performance characteristics of a particular set of electronics. The ADUM3221AEBZ evaluation and demonstration board, from Analog Devices, is a reliable and efficient product used to study voltage regulators, power conversion, galvanic isolation, and analog-to-digital isolation. This board combines two, 3-channel digital isolator ICs with a 3.3V output current limited regulator. The board is designed to study galvanic isolation and evaluate the ADuM3221 digital isolator IC.

The ADuM3221AEBZ has an operating temperature range of -40 to + 85°C. It is provided with a variety of features such as two, 3-channel digital isolator ICs, wide operating temperature range, an isolation voltage of 2500 V, a 10/11 (off/on) power-on reset input, a status flag output,and an output enable input. The board is also UL approved, FCC certified, and rated for 1-3kVrms isolation.

The board takes into consideration board layout, electrical characteristics, and output voltage. The board can be used to study the evaluation of an isolation regulatory loop, evaluate board-level EMI performance, and test line isolation. The EVAL-ADuM3221AEBZ is ideal for applications such as motor control, robotics controllers, home and lighting control systems, and digital power supplies.

The working principle of the EVAL-ADuM3221AEBZ evaluation and demonstration board is quite simple. The board contains two independent 3-channel isolators, ADuM3221 and ADuM3221A, with dual 3-channel VI/O auto-select and an in-circuit programmable interface. An adjustable high voltage regulator is also present on the board, which provides a highly stable 10kV/V (25Vp-p)threshold for signal crossing. The two digital isolator ICs are connected in series on the board, allowing for electrical isolation of two different circuits.

In addition, the board has two 2.2uH MAX4457 ferrite transformer cores, which provide protection against EMI. The board also contains an onboard protection circuit which is used to protect the circuits from over-voltage and over-current. This protection circuit provides overload and thermal protection of the overall system.

The ADuM3221AEBZ evaluation and demonstration board is a reliable and efficient tool used to study voltage regulators, power conversion, galvanic isolation, and analog-to-digital isolation. It is ideal for applications such as motor control, robotics controllers, home and lighting control systems, and digital power supplies. The working principle of the board is based on its two independent 3-channel isolators, an adjustable high voltage regulator, two 2.2uH MAX4457 ferrite transformer, and an onboard protection circuit.
