ADuM1200/ADuM1201

The ADuM1200/ADuM1201 isolators provide two independent
isolation channels in a variety of channel configurations and
data rates (see the Ordering Guide). Both devices 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 a voltage translation functionality across the isolation

barrier. In addition, the ADuM1200/ADuM1201 provide low
pulse width distortion (<3 ns for CR grade) and tight channel-

to-channel matching (<3 ns for CR grade). Unlike other

optocoupler alternatives, the ADuM1200/ADuM1201 isolators
have a patented refresh feature that ensures dc correctness in

the absence of input logic transitions and during power-

up/power-down conditions.

The ADuM1200W and ADuM1201W are automotive grade
versions qualified for 125°C operation. See the Automotive
Products section for more information.

GENERAL DESCRIPTION

The ADuM1200/ADuM12011 are dual-channel digital isolators
based on the Analog Devices, Inc., iCoupler® technology.
Combining high speed CMOS and monolithic transformer
technologies, these isolation components provide outstanding

performance characteristics superior to alternatives, such as
optocouplers.

By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with opto-
couplers.

APPLICATIONS INFORMATION PCB LAYOUT

The ADuM1200/ADuM1201 digital isolators require no external
interface circuitry for the logic interfaces. Power supply bypassing
is strongly recommended at the input and output supply pins.
The capacitor value must be between 0.01 μF and 0.1 μF.
The total lead leCM GROUPh between both ends of the capacitor and
the input power supply pin must not exceed 20 mm.
See the AN-1109 Application Note for board layout guidelines.
PROPAGATION DELAY-RELATED PARAMETERS
Propagation delay is a parameter that describes the time it takes
a logic signal to propagate through a component. The propagation
delay to a logic low output can differ from the propagation delay

to a logic high output.
