GENERAL DESCRIPTION
The ADuM340xW
1
are 4-channel digital isolators based on the
Analog Devices, Inc., iCoupler® technology. Combining high
speed CMOS and monolithic air core transformer technology,
these isolation components provide outstanding performance
characteristics superior to alternatives such as optocoupler devices.
iCoupler devices remove the design difficulties commonly
associated with optocouplers. Typical optocoupler concerns
regarding uncertain current transfer ratios, nonlinear transfer
functions, and temperature and lifetime effects are eliminated
with the simple iCoupler digital interfaces and stable performance
characteristics. The need for external drivers and other discrete
components is eliminated with these iCoupler products. Further-
more, iCoupler devices consume one-tenth to one-sixth the power
of optocouplers at comparable signal data rates.
The ADuM340xW isolators provide four independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). All models of the ADuM340xW
provide operation from 3.135 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage level translation function across the isolation barrier. The
ADuM340xW isolators have a patented refresh feature that ensures
dc correctness in the absence of input logic transitions and
during power-up/power-down conditions.
The ADuM340xW isolators contain various circuit and layout
changes to provide increased capability relative to system-level IEC
61000-4-x testing (ESD/burst/surge). The precise capability in
these tests is strongly determined by the design and layout of
the user’s board or module. For more information, see the
AN-793 Application Note, ESD/Latch-Up Considerations with
iCoupler Isolation Products.
