GENERAL DESCRIPTION
The ADuM340x
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 ADuM340x isolators provide four independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). All models operate with the supply
voltage on either side ranging from 2.7 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier. The
ADuM340x isolators have a patented refresh feature that ensures dc
correctness in the absence of input logic transitions and during
power-up/power-down conditions.
In comparison to the ADuM140x isolators, the ADuM340x
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 for either
the ADuM140x or ADuM340x products is strongly determined by
the design and layout of the user’s board or module. For more
information, see the
Considerations with iCoupler Isolation Products.
