GENERAL DESCRIPTION

The ADuM210N1 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 ADuM210N supports data rates as high as 150 Mbps with a

withstand voltage rating of 5.0 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.
