GENERAL DESCRIPTION
The EVAL-ADuM3150Z supports the ADuM3150ARSZ and
ADuM3150BRSZ, which are 6-channel SPIsolator® isolators
optimized for use in SPI applications. They include two low
speed channels and a clock delay channel for the implementation
of 40 MHz SPI data transfers. 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 EVAL-ADuM3150Z evaluation board can be used to
evaluate the ADuM4150ARIZ and the ADuM4150BRIZ
devices. Although the pad layout on the EVAL-ADuM3150Z
evaluation board does not support the ADuM4150ARIZ and
the ADuM4150BRIZ 20-lead SOIC_IC packages, these devices can
be evaluated with the ADuM3150ARSZ or the ADuM3150BRSZ.
The ADuM4150ARIZ and ADuM3150ARSZ differ by package
and isolation capabilities, but are functionally equivalent for
evaluation. The same is true for the ADuM4150BRIZ and
ADuM3150BRSZ devices.
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
electromagnetic interference (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.
For full details, see the ADuM3150 data sheet, which must be
used in conjunction with this user guide when using the EVAL-
ADuM3150Z evaluation board.
