Analog Devices has added two galvanically-isolated RS-485/422 transceivers, each featuring an integrated isolated power converter.

The ADM2587E and ADM2582E are its first to integrate a line driver, line receiver, regulator, and transformers into a single-chip that isolates both the data and power lines in a 10x13mm surface mount package.

The device provides +/-15kV ESD protection on bus pins for a communications interface with isolated power for use in harsh industrial and instrumentation environments.

The RS-485/422 transceivers feature both data-line and power isolation, based on the company’s iCoupler and isoPower isolation technologies.

With a 2.5-kV isolation rating, the new RS-485/422 transceiver complies with industry-standard isolation regulations, including UL1577 and DIN VDE 0884-10, and so will meet the robustness levels required in noisy operating environments such as programmable logic controllers, distributed control systems, motor controls, building control systems, industrial fieldbus, and telecom equipment.
