GENERAL DESCRIPTION
The ADuM220N/ADuM221N/ADuM225N/ADuM226N1 are
dual-channel digital isolators based on Analog Devices, Inc.,
iCoupler® technology. Combining high speed, complementary
metal-oxide semiconductor (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. The
maximum propagation delay is 13 ns with a pulse width distortion
(PWD) of less than 3 ns at 5 V operation. Channel matching is
tight at 3.0 ns maximum.
The ADuM220N/ADuM221N/ADuM225N/ADuM226N data
channels are independent and are available in a variety of
configurations with a withstand voltage rating of 5.0 kV rms (see
the Ordering Guide). The devices operate with the supply voltage
on either side ranging from 1.8 V to 5 V, providing compatibil-
ity with lower voltage systems as well as enabling voltage translation
functionality across the isolation barrier. Unlike other optocoupler
alternatives, dc correctness is ensured in the absence of input logic
transitions. Two different fail-safe options are available, in which
