Overview
The ADM2682EBRIZ is a highly integrated, signal and power isolated RS-485 transceiver produced by Analog Devices Inc. This device is designed for balanced transmission lines and complies with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E) standards. It integrates iCoupler® technology, combining a 3-channel isolator, a three-state differential line driver, a differential input receiver, and an isoPower® dc-to-dc converter into a single package. The ADM2682EBRIZ operates on a single 5 V or 3.3 V supply, providing a fully integrated isolated RS-485 solution.
