GENERAL DESCRIPTION
The ADuM240x
Devices, Inc., iCoupler® technology. Combining high speed CMOS
and monolithic air core transformer technology, these isolation
components provide outstanding performance characteristics that
are superior to alternatives, such as optocoupler devices.
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with opto-
couplers. The typical optocoupler concerns regarding uncertain
current transfer ratios, nonlinear transfer functions, and
temperature and lifetime effects are eliminated with the simple
1
pending.

iCoupler digital interfaces and stable performance characteristics.
Furthermore, iCoupler devices run at one-tenth to one-sixth
the power of optocouplers at comparable signal data rates.
The ADuM240x isolators provide four independent isolation
channels in a variety of channel configurations and data rates (see
the Ordering Guide). The ADuM240x models operate with the
supply voltage of 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 ADuM240x provide low pulse width distortion (<2 ns
for CRWZ grade) and tight channel-to-channel matching (<2 ns
for CRWZ grade). Unlike other optocoupler alternatives, the
ADuM240x isolators have a patented refresh feature that ensures dc
correctness in the absence of input logic transitions and during
power-up/power-down conditions.
