APPLICATIONS
ADuM1400 / ADuM1401 / ADuM1402
GENERAL DESCRIPTION
The ADuM140x 1 are quad-channel digital isolators based on
Analog Devices, Inc., i Coupler? technology. Combining high
speed CMOS and monolithic air core transformer technology,
these isolation components provide outstanding performance
characteristics superior to alternatives, such as optocoupler
devices.
By avoiding the use of LEDs and photodiodes, i Coupler 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
i Coupler digital interfaces and stable performance characteristics.
The need for external drivers and other discrete components
is eliminated with these i Coupler products. Furthermore,
i Coupler devices consume one-tenth to one-sixth of the power
of optocouplers at comparable signal data rates.
The ADuM140x isolators provide four independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). All models 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 ADuM140x provides low pulse width distortion
(<2 ns for CRW grade) and tight channel-to-channel matching
(<2 ns for CRW grade). Unlike other optocoupler alternatives,
the ADuM140x isolators have a patented refresh feature that
ensures dc correctness in the absence of input logic transitions
and when power is not applied to one of the supplies.
