GENERAL DESCRIPTION
The ADuM3210/ADuM3211
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 charac-
teristics superior to alternatives such as optocoupler devices.
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with opto-
couplers. 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 characteristics. 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 ADuM3210/ADuM3211 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 func-
tionality across the isolation barrier. The ADuM3210/ADuM3211
isolators have a default output low characteristic in comparison
to the ADuM3200/ADuM3201 models, which have a default output
high characteristic. The
ADuM3210W and ADuM3211W models
are automotive grade versions qualified for 125°C operation.
In comparison to the ADuM1200/ADuM1201 isolator, the
ADuM3210/ADuM3211 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/ADuM1201 or
ADuM3210/ADuM3211 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.
