GENERAL DESCRIPTION
The ADM2582E/ADM2587E are fully integrated signal and
power isolated data transceivers with ±15 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.
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., 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 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, 20-lead, wide-
body SOIC package.
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-0971, Control of Radiated Emissions with
isoPower Devices, for details on board layout considerations.
