Product Summary
The ADM2483BRWZ is a differential bus transceiver. It is an integrated, galvanically isolated component designed for bidirectional data communication on balanced, multipoint bus transmission lines. It complies with ANSI TIA/EIA RS-485-A and ISO 8482:1987(E). Using Analog Devices’ iCoupler technology, the ADM2483BRWZ combines a 3-channel isolator, a 3-state differential line driver, and a differential input receiver into a single package. The applications of the ADM2483BRWZ include Low power RS-485/RS-422 networks, Isolated interfaces, Building control networks and Multipoint data transmission systems.
