- Installed SPIsolator® digital isolator: ADuM3151BRSZ in the 20-lead SSOP package
The EVAL-ADuM3151Z supports the parts listed in the supported models section, which are, 7-channel, data direction variants of SPIsolator® isolators optimized for use in SPI applications. They include three low speed channels for axillary functions, which are not timing critical. 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 bypass capacitance. Signal sources 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.
