Product Details

The EVAL-ADuM32XNEBZ evaluation board supports simplified, efficient evaluation of the 3 kV RMS ADuM320N/ADuM321N family of iCoupler^® digital isolators. The EVAL-ADuM32XNEBZ evaluation board also grants the ability to examine multiple other 8-lead SOIC_N iCoupler digital isolators through the unpopulated U3, which provides the user a JEDEC standard 8-Lead SOIC_N pad layout and routing appropriate for the evaluation of supported devices.

The EVAL-ADuM32XNEBZ evaluation board features V shaped grooves between each component (U1 to U3) that allow the user to split the PCB into sections and examine a specific device of their choice on a breadboard or similar prototyping board for ease of use. If U3 is populated with a different supported device, refer to the appropriate device data sheet.

Power and the inputs/outputs can be connected either directly to the pin header connectors or onto a prototyping board.

The EVAL-ADuM32XNEBZ evaluation board follows printed circuit board (PCB) design practices, including a ground plane on each side of the isolation barrier. No other electromagnetic interference (EMI) or noise mitigation design features are included on this board.

Full specifications for the device under test (DUT) are available in the ADuM320N/ADuM321N data sheet available from Analog Devices, Inc., and must be consulted with the user guide when using the EVAL-ADuM32XNEBZ evaluation board.
