1. DESCRIPTION
The ADM2582EBRWZ-REEL7 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 ADM2582EBRWZ-REEL7 include an integrated isolated dc-to-dc power supply, which eliminates the need for an external dc-to-dc isolation block. 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-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. The ADM2582EBRWZ-REEL7 driver has an active high enable. An active low receiver enable is also provided, which causes the receiver output to enter a high impedance state when disabled. The devices have current limiting and thermal shutdown features to protect against output short circuits and situations where bus contention may cause excessive power dissipation. The parts are fully specified over the industrial temperature range and are available in a highly integrated, 20-lead, wide-body SOIC package. The ADM2582EBRWZ-REEL7 contain isoPower technology that uses high frequency switching elements to transfer power through the transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. Refer to the AN-0971 Application Note, Control of Radiated Emissions with isoPower Devices, for details on board layout considerations.
