GENERAL DESCRIPTION
The ADuM110N is a single-channel digital isolator based on
Analog Devices, Inc., iCoupler® technology. Combining high
speed, complementary metal-oxide semiconductor (CMOS)
and monolithic air core transformer technology, this isolation
component provides 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 3 ns at 5 V operation.
The ADuM110N supports data rates as high as 150 Mbps with a
withstand voltage rating of 3.0 kV rms (see the Ordering Guide).
The device operates with the supply voltage on either side
ranging from 1.8 V to 5 V, providing compatibility 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 the outputs transition to a pre-
determined state when the input power supply is not applied or
the inputs are disabled. The ADuM110N is pin compatible with
the ADuM1100.
