The ADM2582E/ADM2587E are fully integrated signal and power isolated data transceivers with ±15 kV ESD protection and are suitable for high speed communication on multipoint transmission lines. The ADM2582E/ADM2587E include an integrated isolated dc-to-dc power supply， which 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 DevicesisoPower dc-to-dc 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.
