GENERAL DESCRIPTION
The ADuM140x are 4-channel digital isolators based on Analog
Devices’
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
optocouplers. 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 discretes
is eliminated with these
i
Coupler products. Furthermore,
i
Coupler devices consumes one-tenth to one-sixth 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
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 during power-up/power-down conditions.
