ADM2582EBRMZ

Product Overview

ADM2582EBRMZ is an Analog Devices fully integrated signal and power isolated RS-485 / RS-422 transceiver designed for reliable isolated serial communication on balanced transmission lines. The device combines iCoupler® digital isolation, a differential line driver, a differential receiver and an isoPower® isolated dc-to-dc converter in one compact package. With ±15kV ESD protection on the RS-485 bus pins, 16Mbps data rate capability and 2.5kVrms isolation, it is suitable for industrial automation, motor control, isolated communication ports, instrumentation and harsh-noise communication environments.
