Overview
The ADM2582EBRWZ from Analog Devices Inc. is a fully integrated signal and power isolated RS-485/RS-422 data transceiver. This device is designed for high-speed communication on multipoint transmission lines and features ±15 kV ESD protection. It integrates Analog Devices' iCoupler® technology, which includes a 3-channel isolator, a three-state differential line driver, a differential input receiver, and an isoPower® dc-to-dc converter. This integration eliminates the need for an external dc-to-dc isolation block, providing a comprehensive solution for isolated RS-485 applications.
