GENERAL DESCRIPTION
The ADuM3480/ADuM3481/ADuM34821 are quad-channel
digital isolators based on the 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
typical propagation delay reduced to 25 ns, pulse width
distortion is also halved.
The four channels of the ADuM3480/ADuM3481/ADuM3482
are available in a variety of channel configurations with two data
rate grades up to 25 Mbps (see the Ordering Guide section). All
models use separate core and I/O power supplies. The core
operates between 3.0 V and 5.5 V, whereas the I/O supply can
range from 1.8 V to 5.5 V.If I/O operation is required within
the range of the core supply, the two supplies can be tied together
to allow single-supply operation. When the I/O must interface
with logic levels that are different from the core supply voltage,
the I/O supply operates independently of the core supply over
its wider range. The minimum I/O supply voltage is 1.8 V, which
allows compatibility with low voltage logic. Both core and I/O
supplies are required for proper operation.
