GENERAL DESCRIPTION
The ADuM320x
Analog Devices’ 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
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 ADuM320x isolators provide two independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). Both parts 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 a
voltage translation functionality across the isolation barrier. The
ADuM320x isolators have a patented refresh feature that ensures
dc correctness in the absence of input logic transitions and
during power-up/power-down conditions.
In comparison to the ADuM120x isolators, the ADuM320x
isolators contain various circuit and layout changes to provide
increased capability relative to system-level IEC 61000-4-x
testing (ESD, burst, surge). The precise capability in these tests
for either the ADuM120x or ADuM320x products is strongly
determined by the design and layout of the user’s board or
module. For more information, see
ESD/Latch-Up Considerations with iCoupler Isolation
