Triple-Channel Digital Isolators
GENERAL DESCRIPTION
The ADuM130x
are triple-channel digital isolators based on the
Analog Devices, Inc.,
iCoupler®
technology. Combining high
speed CMOS and monolithic transformer technology, 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
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
of the power of optocouplers at comparable signal data rates.
The ADuM130x isolators provide three independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). Both 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 ADuM130x provide 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 ADuM130x 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.
