APPLICATIONS

General-purpose, unidirectional, multichannel isolation

GENERAL DESCRIPTION

The ADuM13101 is a unidirectional, triple-channel digital

isolator based on Analog Devices, Inc. iCoupler® technology.

Combining high speed CMOS and monolithic coreless trans-

former technology, this isolation component provides 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 concerns that arise with opto-

couplers, such as 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 discretes is eliminated with these iCoupler products.

Furthermore, iCoupler devices run at one-tenth to one-sixth

the power consumption of optocouplers at comparable signal

data rates.

The ADuM1310 isolator provides three independent isolation

channels at data rates up to 10 Mbps. It operates with the supply

voltage of 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.

This product also has a default output control pin. This allows

the user to define the logic state the outputs are to adopt in the

alternatives, the ADuM1310 has a patented refresh feature that

ensures dc correctness in the absence of input logic transitions

and during power-up/power-down conditions.
