Dual-Channel Digital Isolator
Data Sheet
ADuM1200-EP
FEATURES
GENERAL DESCRIPTION
Narrow body, 8-lead SOIC package
Low power operation
5 V operation
The ADuM1200-EP1 is a dual-channel, digital isolator based on
the Analog Devices, Inc., iCoupler® technology. Combining
high speed CMOS and monolithic transformer technologies,
this isolation component provides outstanding performance
characteristics superior to alternatives, such as optocouplers.

UL recognition
2500 V rms for 1 minute per UL 1577
CSA Component Acceptance Notice #5A
VDE Certificate of Conformity
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, nonlinear transfer functions, and tem-
perature 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 ADuM1200-EP isolator provides two independent isolation
channels with a supply voltage on either side ranging from 3.0 V
to 5.5 V. In addition, the ADuM1200-EP provides low pulse width
distortion and tight channel-to-channel matching. Unlike other
optocoupler alternatives, the ADuM1200-EP isolator has a
patented refresh feature that ensures dc correctness in the absence
of input logic transitions and during power-up/ power-down
conditions.
