GENERAL DESCRIPTION

The ADuM1300/ADuM13011 are triple-channel digital isolators

based on the Analog Devices, Inc., iCoupler? technology.

Combining high speed CMOS and monolithic transformer

technology, 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 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 of the power of

optocouplers at comparable signal data rates.

The ADuM1300/ADuM1301 isolators provide three independent

isolation channels in a variety of channel configurations and

data rates (see the Ordering Guide). Both 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 a voltage translation functionality across the isolation

barrier. In addition, the ADuM1300/ADuM1301 provide low

pulse width distortion (<2 ns for CRW grade) and tight channelto-

channel matching (<2 ns for CRW grade). Unlike other

optocoupler alternatives, the ADuM1300/ADuM1301 isolators

have a patented refresh feature that ensures dc correctness in the

absence of input logic transitions and when power is not applied

to one of the supplies.
