GENERAL DESCRIPTION  
5
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.

Figure 2. ADuM3481  
ADuM3482  
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.
