The EVAL-ADuM1241EBZ supports the ADuM1240ARSZ, ADuM1241ARSZ, ADuM1245ARSZ, and ADuM1246ARSZ, which are ultralow power, 2-channel iCoupler® isolators. The evaluation board provides a JEDEC standard 20-lead SSOP pad layout, support for signal distribution, loopback, and loads referenced to VDDx or GNDx, as well as optimal by pass capacitance. Signal sources can be wired onto the board as well as brought on to the board through edge-mounted SMA connectors (sold separately) or terminal blocks for power connections. The board includes 200mil 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.
