APPLICATIONS
General-purpose multichannel isolation
Data converter isolation
Industrial field bus isolation
Hybrid electric vehicles, battery monitor, and motor drive
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 and other integrated couplers.
With propagation delay at 20 ns, pulse width distortion is less
than 2 ns for C grade. Channel-to-channel matching is tight at
5 ns for C grade. The two channels of the ADuM128x are
independent isolation channels and are available in two channel
configurations with three different data rates up to 100 Mbps
(see the Ordering Guide). Industrial grade models operate with
the supply voltage on either side ranging from 2.7 V to 5.5 V
while automotive grades operate from 3.0 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier.
Unlike other optocoupler alternatives, the ADuM128x isolators
have a patented refresh feature that ensures dc correctness in
the absence of input logic transitions. When power is first
applied or is not yet applied to the input side, the ADuM1280
and ADuM1281 have a default high output, and the ADuM1285
and ADuM1286 have a default low output.
