GENERAL DESCRIPTION

The ADuM120x are dual-channel digital isolators based on

Analog Devices’ iCoupler® technology. Combining high speed

CMOS and monolithic 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, nonlinear 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 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 ADuM120x isolators provide two independent isolation

channels in a variety of channel configurations and data rates

(see the Ordering Guide). Both parts 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 ADuM120x 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

ADuM120x isolators have a patented refresh feature that

ensures dc correctness in the absence of input logic transitions

and during power-up/power-down conditions.
