3 kV RMS Dual Channel Digital Isolators

Data Sheet

ADuM1280/ADuM1281/ADuM1285/ADuM1286

FEATURES

GENERAL DESCRIPTION

Up to 100 Mbps data rate (NRZ)

Low propagation delay: 20 ns typical

Low dynamic power consumption

Bidirectional communication

3 V to 5 V level translation

High temperature operation: 125°C

The ADuM1280/ADuM1281/ADuM1285/ADuM1286¹(also

referred to as ADuM128x in this data sheet) are dual-channel

digital isolators based on the Analog Devices, Inc., iCoupler®

technology. Combining high speed CMOS and monolithic air

core transformer technology, these isolation components

provide outstanding performance characteristics superior to

High common-mode transient immunity: >25 kV/μs

Default high output: ADuM1280/ADuM1281

Default low output: ADuM1285/ADuM1286

Narrow body, RoHS-compliant, 8-lead SOIC

Safety and regulatory approvals (pending)

UL recognition: 3000 V rms for 1 minute per UL 1577

CSA Component Acceptance Notice #5A

alternatives, such as optocoupler devices and other integrated

couplers.

With propagation delay at 20 ns, pulse width distortion is less

than 2 ns for C grade. Channel-to-channel matching is tight at

5 ns for C grade. The two channels of the ADuM128x are

independent isolation channels and are available in two channel

configurations with three different data rates up to 100 Mbps

(see the Ordering Guide). All 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.

Unlike other optocoupler alternatives, the ADuM128x isolators

have a patented refresh feature that ensures dc correctness in

the absence of input logic transitions. When power is first

applied or is not yet applied to the input side, the ADuM1280

and ADuM1281 have a default high output, and the ADuM1285

and ADuM1286 have a default low output.

VDE Certificate Of Conformity
