GENERAL DESCRIPTION
The ADuM1310/ADuM13111 are 3-channel digital isolators
based on Analog Devices, Inc., iCoupler® technology. Combin-
ing high speed CMOS and monolithic air core transformer
technology, these isolation components provide outstanding
performance characteristics superior to alternatives such as
optocoupler devices.
comparable signal data rates. The iCoupler also offers higher
channel densities and more options for channel directionality.
The ADuM1310/ADuM1311 isolators provide three
independent isolation channels in a variety of channel
configurations and data rates up to 10 Mbps (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 voltage translation
functionality across the isolation barrier. All products allow the
user to predetermine the default output state in the absence of input
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with opto-
couplers. The typical optocoupler concerns regarding uncertain
current transfer ratios, maximum operating 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
V
DD1 power with a simple control pin. Unlike other optocoupler
alternatives, the ADuM1310/ADuM1311 isolators have a patented
refresh feature that ensures dc correctness in the absence of input
logic transitions and during power-up/ power-down conditions.
