GENERAL DESCRIPTION
The ADuM240x are four-channel digital isolators based on
Analog Devices’
i
Coupler 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. In comparison to the 2.5KV ADuM140x product
family, ADuM240x models have increased insulation thickness
to achieve the higher 5.0KV isolation rating.
By avoiding the use of LEDs and photodiodes,
i
Coupler 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,
i
Coupler digital interfaces and stable performance
characteristics. The need for external drivers and other discretes
is eliminated with these
i
Coupler products. Furthermore,
i
Coupler devices run at one-tenth to one-sixth the power
consumption of optocouplers at comparable signal data rates.
The ADuM240x isolators provide four independent isolation
channels in a variety of channel configurations and data rates (see
Ordering Guide). All ADuM240x models operate with the supply
voltage of 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. In
addition, the ADuM240x provides low pulse width distortion (<2
ns for CRWZ grade), and tight channel-to-channel matching (<2
ns for CRWZ grade). Unlike other optocoupler alternatives, the
ADuM240x isolators have a patented refresh feature that ensures
dc correctness in the absence of input logic transitions and during
power-up/power-down conditions.
