GENERAL DESCRIPTION
The ADuM3210¹ is a dual-channel, digital isolator 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 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 charac-
teristics. 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 isolator provides two independent isolation
channels. It operates 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 voltage translation functionality
across the isolation barrier. The ADuM3210 has a default output
low characteristic in comparison to the ADuM3200/ADuM3201
models that have a default output high characteristic. The
ADuM3210 is also available in 125°C temperature grade.
In comparison to the ADuM1210 isolator, the ADuM3210
isolator contains 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 ADuM1210 or ADuM3210 products is strongly
determined by the design and layout of the user’s board or
module. For more information, see AN-793 Application Note,
ESD/Latch-Up Considerations with iCoupler Isolation Products.
