GENERAL DESCRIPTION

The ADM2582E/ADM2587E are fully integrated signal and

power isolated data transceivers with ±±5 kV ESD protection

and are suitable for high speed communication on multipoint

transmission lines. The ADM2582E/ADM2587E include an

integrated isolated dc-to-dc power supply, which eliminates the

need for an external dc-to-dc isolation block.

The ADM2582E/ADM2587E driver has an active high enable.

An active low receiver enable is also provided that causes the

receiver output to enter a high impedance state when disabled.

The devices have current limiting and thermal shutdown

features to protect against output short circuits and situations

where bus contention may cause excessive power dissipation.

The parts are fully specified over the industrial temperature

range and are available in a highly integrated, 20-lead, wide-

body SOIC package.

They are designed for balanced transmission lines and comply

with ANSI/TIA/EIA-485-A-98 and ISO 8482:±987(E).

The devices integrate Analog Devices, Inc., iCoupler® technology to

combine a 3-channel isolator, a three-state differential line driver, a

differential input receiver, and Analog Devices isoPower dc-to-

dc converter into a single package. The devices are powered by a

single 5 V or 3.3 V supply, realizing a fully integrated signal and

power isolated RS-485 solution.

The ADM2582E/ADM2587E contain isoPower technology that

uses high frequency switching elements to transfer power through

the transformer. Special care must be taken during printed circuit

board (PCB) layout to meet emissions standards. Refer to

Application Note AN-097±, Control of Radiated Emissions with

isoPower Devices, for details on board layout considerations.
