GENERAL DESCRIPTION
The ADuM321x
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 two channels of the ADuM321x are independent isolation
channels and are available in two channel configurations with
two different data rates up to 10 Mbps (see the Ordering Guide).
They operate 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 ADuM321x isolators have a default
output low characteristic in comparison to the ADuM3200/
ADuM3201
The ADuM321x are also available in 125°C temperature grade.
In comparison to the
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 ADuM321x 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.
