GENERAL DESCRIPTION
The ADuM3210-EP/ADuM3211-EP
1
are dual-channel digital
isolators based on Analog Devices, Inc., iCoupler® technology.
Combining high speed CMOS and monolithic transformer
technology, this isolation component provides outstanding
performance characteristics superior to alternatives such as
optocoupler devices.
The ADuM3210-EP/ADuM3211-EP isolators provide two
independent isolation channels in two channel configurations
with data rates up to 25 Mbps (see the Ordering Guide). They
operate with 3.3 V or 5 V supply voltages on either side,
providing compatibility with lower voltage systems, as well as
enabling voltage translation functionality across the isolation
barrier. The ADuM3210-EP/ADuM3211-EP isolators have a
default output low characteristic in comparison to the
ADuM3200/ADuM3201 models, which have a default output high
characteristic.
In comparison to the ADuM1200-EP isolator, the
ADuM3210-EP/ADuM3211-EP isolators contain various
circuit and layout changes providing increased capability relative
to system-level IEC 61000-4-x testing (ESD, burst, and surge). The
precise capability in these tests for either the ADuM1200-EP or
ADuM3210-EP/ADuM3211-EP products 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.
Refer to the ADuM3210/ADuM3211 data sheet for additional
application and technical information.
