GENERAL DESCRIPTION
The E VA L-ADuM1241EBZ supports the ADuM1240ARSZ,
ADuM1241ARSZ, ADuM1245ARSZ, and ADuM1246ARSZ,
which are ultralow power, dual-channel iCoupler® isolators. The
evaluation board provides a JEDEC standard 20-lead SSOP pad
layout, support for signal distribution, loopback, and loads
referenced to V
DDx
or GND
x
, 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.
