GENERAL DESCRIPTION

TheADUM3301CRWZ/ADuM33011

are 3-channel digital isolators based

on the Analog Devices, Inc., iCoupler® technology. Combining

high speed CMOS and monolithic air core transformer technology,

these isolation components provide outstanding performance

characteristics superior to alternatives, such as optocoupler devices.

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 consume one-tenth to one-sixth

the power of optocouplers at comparable signal data rates.

The ADuM3300/ADuM3301 isolators provide three independent

isolation channels in a variety of channel configurations and

data rates (see the Ordering Guide). All models operate with the

supply voltage on either side ranging from 3.3 V to 5.5 V, providing

compatibility with lower voltage systems as well as enabling a

voltage translation functionality across the isolation barrier. The

ADuM3300/ADuM3301 isolators have a patented refresh feature

that ensures dc correctness in the absence of input logic

transitions and during power-up/power-down conditions.

In comparison to ADUM3301CRWZ/ADuM1301 isolators, ADUM3301CRWZ/

ADUM3301CRWZ isolators contain various circuit and layout changes

to provide increased capability relative to system-level IEC

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

in these tests for either the ADuM1300/ADuM1301 or

ADuM3300/ADUM3301CRWZ products is strongly determined by the

design and layout of the user’s system.
