ADuM3300/ADuM3301
GENERAL DESCRIPTION
The ADuM330x1 are 3-channel digital isolators based on the
Analog Devices, Inc.iCoupler® technology. Combining high
peed
s
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 ADuM330x 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 2.7 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier. The
ADuM330x 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 ADuM130x isolators, ADuM330x 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 ADuM130x or ADuM330x products is strongly determined
by the design and layout of the user’s system.

the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with
