GENERAL DESCRIPTION
The ADuM3300/ADuM3301
1
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 ADuM1300/ADuM1301 isolators, ADuM3300/
ADuM3301 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/ADuM3301 products is strongly
determined by the design and layout of the user’s system.
