The ADM2682E/ADM2687E are fully integrated 5 kV rms signal and power isolated data transceivers with ±15 kV

ESD protection and are suitable for high speed communication on multipoint transmission lines.

The ADM2682E/ADM2687E include an integrated 5 kVrms i solated dc-to-dc power supply, which eliminates the need for an external dc

-to-dc isolation block. They aredesigned for balanced transmissi on lines and comply with ANSI/TIA/EIA-485-A-98 and ISO8482:1987(E).

The devices integrate Analog Devices, Inc.,i Coupler® technology to combine a 3-channel isolator, a three-state differential line driver,

a differential input receiver, and Analog Devices iso Power dc-to-dc converter into a single package.

The devices are powered by a single 5V or 3.3V supply, realizing a fully integrated signal and power isolated RS-485 solution.

The ADM2682E/ADM2687E driver has an active high enable. An active low receiver enable is also provided, which

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, 16-lead, wide-body

SOIC package with >8 mm creepageand clearance

The ADM2 682E/ADM2687E contain iso Power 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-0971, Control of Radiated Emissions with isoPower Devices, for details on board layout considerations.
