ADM2485BRWZ-REEL7

ADM2485 is a differential bus transceiver with an integrated, galvanically isolated component designed for bidirectional data communication on multipoint bus transmission lines. It is designed for balanced transmission lines and complies with ANSI/TIA/EIA RS-485-A-98 and ISO 8482:1987(E). The device employs Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator, a three-state differential line driver, and a differential input receiver into a single package. An on-chip oscillator outputs a pair of square waveforms that drive an external transformer to provide isolated power with an external transformer. Typical application includes isolated RS-485/RS-422 interfaces, PROFIBUS networks, industrial field networks and multipoint data transmission systems.
