GENERAL DESCRIPTION
The ADuM2280/ADuM2281/ADuM2285/ADuM22861 (also
referred to as ADuM228x in this data sheet) are 5 kV rms dualchannel
digital isolators based on Analog Devices, Inc., iCoupler®
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 24 ns maximum, pulse width
distortion is less than 2 ns for C grade. Channel-to-channel
matching is tight at 5 ns for C grade. The ADuM228x are
available in two channel configurations with three different
data rates up to 100 Mbps (see the Ordering Guide). All 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. Unlike other optocoupler
alternatives, the ADuM228x 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 ADuM2280 and ADuM2281 have a default
high output and the ADuM2285 and ADuM2286 have a default low output.
