GENERAL DESCRIPTION
1
The ADuM120x
are dual-channel, digital isolators based on
the Analog Devices, Inc., iCoupler® technology. Combining
high speed CMOS and monolithic transformer technologies,
these isolation components provide outstanding performance
characteristics superior to alternatives, such as optocouplers.
By avoiding the use of LEDs and photodiodes, iCoupler
devices remove the design difficulties commonly associated

Dual-Channel Digital Isolators
ADuM1200/ADuM1201
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 char-
acteristics. The need for external drivers and other discrete
components is eliminated with these iCoupler products. Further-
more, iCoupler devices consume one-tenth to one-sixth the
power of optocouplers at comparable signal data rates.
The ADuM120x 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.
In addition, the ADuM120x provide low pulse width distortion
(<3 ns for CR grade) and tight channel-to-channel matching
(<3 ns for CR grade). Unlike other optocoupler alternatives,
the ADuM120x isolators have a patented refresh feature that
ensures dc correctness in the absence of input logic transitions
and during power-up/power-down conditions.
ADuM1200W and ADuM1201W are automotive grade versions
qualified for 125°C operation per AEC-Q100. See the
Automotive Products section for more details.
