GENERAL DESCRIPTION
The
EVAL-ADuM7643EBZ
ADuM7641, ADuM7642, and ADuM7643, which are 1 kV,
6-channel iCoupler® isolators. The evaluation board provides a
JEDEC standard 20-lead QSOP 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.
