GENERAL DESCRIPTION
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 kV rms isolated dc-to-dc power supply
that eliminates the need for an external dc-to-dc isolation block.
They are designed for balanced transmission lines and comply
with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(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 5 V or 3.3 V supply, realizing a fully integrated signal and
power isolated RS-485 solution.
The ADM2682E / ADM2687E drivers have 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 creepage and clearance.
The ADM2682E / 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
AN-0971 Application Note , Recommendations for Control of
Radiated Emissions with isoPower Devices , for details on board
layout considerations.
