GENERAL DESCRIPTION
The ADuM120x are dual-channel digital isolators based on
Analog Devices’
i
Coupler technology. Combining high speed
CMOS and monolithic 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 discrete
components is eliminated with these
i
Coupler products.
Furthermore,
i
Coupler 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
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.
