GENERAL DESCRIPTION
The ADuM250N/ADuM251N/ADuM252N1 are 5-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 of less than 4.5 ns at 5 V operation. Channel to
channel matching of propagation delay is tight at 4.0 ns
maximum.
The ADuM250N/ADuM251N/ADuM252N 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 1.7 V to 5.5 V, providing compatibility with
lower voltage systems as well as enabling voltage translation
functionality across the isolation barrier.
FUNCTIONAL BLOCK DIAGRAMS
Figure 1. ADuM250N Functional Block Diagram
Figure 2. ADuM251N Functional Block Diagram
Figure 3. ADuM252N Functional Block Diagram
Unlike other optocoupler alternatives, dc correctness is ensured
in the absence of input logic transitions. Two different fail-safe
options are available by which the outputs transition to a predeter-
mined state when the input power supply is not applied.
