Product Details

The EVAL-ADuM3481EBZ supports the ADuM3480/ ADuM3481/ADuM3482, which are 3750 V isolation rating, 4-channel iCoupler^® isolators. The evaluation board provides a JEDEC standard 20-lead SSOP pad layout, support for signal fanout, and loopback as well as optimal bypass capacitance. Signals can be wired onto the board as well as brought onto the board through edge-mounted SMA connectors (sold separately) or terminal blocks for power connections. The board includes 200 mil header positions for compatibility with Tektronix active probes.

The board follows best printed circuit board (PCB) design practices for 4-layer boards, including a full power and ground plane on each side of the isolation barrier. No other EMI or noise mitigation design features are included on this board. In cases of very high speed operation or when ultralow emissions are required, refer to the AN-1109 application note for additional board layout techniques.
