GENERAL DESCRIPTION

The ADuM321x

Analog Devices, Inc., iCoupler® technology. Combining high

speed CMOS and monolithic transformer technology, this

isolation component provides outstanding performance charac-

teristics superior to alternatives such as optocoupler devices.

By avoiding the use of LEDs and photodiodes, iCoupler

devices remove the design difficulties commonly associated

with optocouplers. The typical optocoupler concerns regarding

uncertain current transfer ratios, nonlinear transfer functions,

and temperature and lifetime effects are eliminated with the

simple iCoupler digital interfaces and stable performance charac-

teristics. The need for external drivers and other discrete

components is eliminated with these iCoupler products.

Furthermore, iCoupler devices consume one-tenth to one-

sixth the power of optocouplers at comparable signal data rates.

The two channels of the ADuM321x are independent isolation

channels and are available in two channel configurations with

two different data rates up to 10 Mbps (see the Ordering Guide).

They operate with the supply voltage on either side ranging

from 2.7 V to 5.5 V, providing compatibility with lower voltage

systems as well as enabling voltage translation functionality across

the isolation barrier. The ADuM321x isolators have a default

output low characteristic in comparison to the ADuM3200/

ADuM3201

The ADuM321x are also available in 125°C temperature grade.

In comparison to the

isolators contain various circuit and layout changes providing

increased capability relative to system-level IEC 61000-4-x

testing (ESD, burst, and surge). The precise capability in these

tests for either the ADuM120x or ADuM321x products is strongly

determined by the design and layout of the user’s board or module.

For more information, see the AN-793 Application Note,

ESD/Latch-Up Considerations with iCoupler Isolation Products.
