GENERAL DESCRIPTION

The ADuM2210/ADuM22111 are 2-channel digital isolators

based on Analog Devices, Inc., iCoupler? technology. Combining

high speed CMOS and monolithic air core transformer technology,

these isolation components provide outstanding performance

characteristics that are 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.

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 characteristics. The need for

external drivers and other discrete components is eliminated with

these iCoupler products. Furthermore, iCoupler devices run at

one-tenth to one-sixth the power of optocouplers at comparable

signal data rates.

The ADuM2210/ADuM2211 isolators provide two independent

isolation channels in a variety of channel configurations and

data rates (see the Ordering Guide). They operate with the

supply voltage of either side ranging from 3.0 V to 5.5 V, providing

compatibility with lower voltage systems as well as enabling voltage

translation functionality across the isolation barrier. The

ADuM2210W and ADuM2211W are automotive grade versions.

Similar to the ADuM3200/ADuM3201 isolators, the ADuM2210/

ADuM2211 isolators contain various circuit and layout

enhancements to provide increased capability relative to systemlevel

IEC 61000-4-x testing (ESD, burst, and surge). The precise

capability in these tests for either the ADuM3200/ ADuM3201 or

ADuM2210/ADuM2211 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.
