The ADuM320N/ADuM321N are dual-channel digital isolators based on Analog Devices, Inc., iCoupler^® technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics and meet CISPR 32/EN 55032 Class B limits at 5 Mbps. The maximum propagation delay is 10 ns with a pulse width distortion of less than 3 ns at 5 V operation. Channel matching is hard at 3.0 ns maximum.

The ADuM320N/ADuM321N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 5.7 kV RMS and 3.0 kV RMS (for more information, see the Ordering Guide section of the data sheet). The devices operate with the supply voltage on either side ranging from 2.25 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier.

Two different fail-safe options are available, by which the outputs transition to a predetermined state when the input power supply is not applied.

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.
