ADuM3210/ADuM3211
GENERAL DESCRIPTION
The ADuM3210/ADuM3211 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.
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 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
functionality across the isolation barrier. The ADuM3210/
ADuM3211 isolators have a default output low characteristic in
comparison to the ADuM3200/ADuM3201 models XIJDI have a
default output high characteristic. ADuM3210W and ADuM3211W
are automotive grade versions qualified for 125°C operation.
In comparison to the ADuM120x 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 ADuM120x 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.
