Product Details

The EVAL-ADuM144x-EBZ supports the ADuM144x family of ultra low power, quad channel isolators. It provides a JEDEC standard QSOP16 pad layout, support for signal distribution, loop back, bypass capacitors and loads referenced to VDDX or GNDX. Signal sources can be wired onto the board as well as brought in through Edge mounted SMA connectors (not provided) or terminal blocks for power connections. The board includes 200 mil header positions for compatibility with Tektronix active probes.

The board follows best PCB design practices for four layer boards, including a full power and ground plane on each side of the isolation barrier. No other EMI or noise mitigation practices are included in this board.
