ADuM1440ARQZ
ADuM1441ARQZ
ADuM1442ARQZ
ADuM1445ARQZ
ADuM1446ARQZ
ADuM1447ARQZ
The EVAL-ADuM144xQSOP16-EBZ supports the
ADuM1440ARQZ, ADuM1441ARQZ, ADuM1442ARQZ,
ADuM1445ARQZ, ADuM1446ARQZ, and ADuM1447ARQZ,
which are ultralow power, 4-channel iCoupler® isolators. The
evaluation board provides a JEDEC standard 16-lead QSOP 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.
