DESCRIPTION
The ADuM140x are four-channel digital isolators based on Analog
Devices’ iCoupler
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, iCoupler devices
remove the design difficulties commonly associated with
optocouplers. The typical optocoupler concerns regarding
uncertain current transfer ratios, non-linear 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 discretes are eliminated
with these iCoupler products. Furthermore, iCoupler devices run
at one-tenth to one-sixth the power consumption of optocouplers
at comparable signal data rates.
The ADuM140x isolators provide four independent isolation
channels in a variety of channel configurations and data rates (see
Ordering Guide). All ADuM140x models operate with the supply
voltage of either side ranging from 2.7V to 5.5V providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier. In
addition, the ADuM140x provides low pulse width distortion (<2 ns
for CRW grade), and tight channel-channel matching (<2 ns for CRW
grade). Unlike other optocoupler alternatives, the ADuM140x
isolators have a patented refresh feature that ensures DC-correctness
in the absence of input logic transitions and during power-up/down
conditions.
