The ADM2682E/ADM2687E from Analog Devices are fully integrated 5 kV rms signal and power-isolated data transceivers with ±15 kV ESD protection, and are suitable for high-speed communication on multipoint transmission lines. The ADM2682E/ADM2687E each include an integrated 5 kV rms isolated DC-to-DC power supply that eliminates the need for an external DC-to-DC isolation block.
They are designed for balanced transmission lines and comply with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E).
The devices integrate Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator, a three-state differential line driver, a differential input receiver, and Analog Devices isoPower® DC-toDC converter into a single package. The devices are powered by a single 5 V or 3.3 V supply, realizing a fully integrated signal and power isolated RS-485 solution.
