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.
