current transfer ratios, nonlinear transfer functions, and temper-
ature 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
(see the Ordering Guide). Both parts 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 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.
The ADuM1200W and ADuM1201W are automotive grade
versions qualified for 125°C operation. See the Automotive
Products section for more information.
