ADuM3200/ADuM3201

GENERAL DESCRIPTION

The ADuM3200/ADuM32011 are dual-channel, digital isola­tors based on the Analog Devices, Inc., iCoupler® technology.
Combining high speed CMOS and monolithic transformer
technology, these isolation components provide outstanding
performance characteristics superior to alternatives such as
optocoupler devices.

By avoiding the use of LEDs and photodiodes, iCoupler
devices remove the design difficulties commonly associated
with optocouplers. The 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 char-
acteristics. The need for external drivers and other discrete
components is eliminated with these iCoupler products. Further­more, iCoupler devices consume one-tenth to one-sixth the
power of optocouplers at comparable signal data rates.

The ADuM3200/ADuM3201 isolators provide two independent
isolation channels in a variety of channel configurations and
data rates (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 ADuM3200W
and ADuM3201W are automotive grade versions qualified
for 125°C operation.

In comparison to the ADuM120x isolators, the ADuM3200/

ADuM3201 isolators contain various circuit and layout changes

to provide increased capability relative to system-level IEC
61000-4-x testing (ESD, burst, and surge). The precise capability
in these tests for either the ADuM120x or ADuM3200/

ADuM3201 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.
