GENERAL DESCRIPTION
The ADuM344x 1 are four channel, digital isolators based on the
Analog Devices, Inc., i Coupler? technology supporting data rates
up to 150 Mbps. Combining high speed CMOS and monolithic
air core transformer technology, these isolation components
provide outstanding performance characteristics superior to
alternatives such as optocoupler devices.
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 discrete
components is eliminated with these i Coupler products.
Figure 3. ADuM3442 Functional Block Diagram
Furthermore, i Coupler devices consume one-tenth to one-sixth
the power of optocouplers at comparable signal data rates.
The ADuM344x isolators provide four independent isolation
channels in a variety of channel configurations (see the
Ordering Guide). The ADuM344x operates with the supply
voltage on 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. In
addition, the ADuM344x provides low pulse width distortion
and tight channel-to-channel matching. Unlike other opto-
coupler alternatives, the ADuM344x isolators have a patented
refresh feature that ensures dc correctness in the absence of
input logic transitions and during the power-up/power-down
condition.
