Overview

The ADM2582EBRWZ-REEL7 is a fully integrated signal and power isolated RS-485/RS-422 transceiver. It combines Analog Devices iCoupler and isoPower technologies into a single 20-lead SOIC package, providing 2500Vrms isolation and 16Mbps data rates without the need for an external DC-to-DC converter.

Why Choose This Part

This device eliminates the need for a separate isolated power supply, significantly reducing PCB area and BOM complexity. It features high common-mode transient immunity of 25kV/us and is rated for a wide industrial temperature range from -40C to +85C.

Applications

Industrial Field Networks
Ideal for Modbus, PROFIBUS, and other fieldbus protocols in electrically noisy factory environments.
Multipoint Data Transmission
Used in building automation and HVAC control systems where long cable runs require common-mode voltage rejection.
Isolated RS-485/RS-422 Interfaces
Provides ground loop elimination and protection for sensitive logic circuitry in energy metering and solar inverters.

Getting Started

Designers should place 0.1uF and 10uF bypass capacitors as close to the VCC and VISOUT pins as possible to maintain power stability. Evaluate performance using the EVAL-ADM2582EEBZ development board, and ensure the PCB layout follows isolation creepage and clearance requirements for 2500Vrms ratings.
