ADM2687EBRIZ

产品概述

The ADM2687EBRIZ is a fully integrated 5kVrms signal and power isolated Data Transceiver with ±15kV ESD protection and are suitable for high speed communication on multipoint transmission lines. It includes an integrated 5kVrms isolated DC-to-DC power supply that eliminates the need for an external DC-to-DC isolation block. This ADM2687EBRIZ designed for balanced transmission lines and comply with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E). The devices integrate Analogue Devices, Inc., iCoupler® technology to combine a 3-channel isolator, a three-state differential line driver, a differential input receiver and Analogue Devices isoPower® DC-to-DC converter into a single package. The devices are powered by a single 5 or 3.3V supply, realizing a fully integrated signal and power isolated RS-485 solution. The driver has an active high enable.
