ADM485AR Description

Short technical summary and product information.

The ADM485AR is a differential line transceiver from Analog Devices designed for high speed bidirectional data communication on multipoint bus transmission lines. It complies with EIA standards RS-485 and RS-422. The device integrates one differential driver and one differential receiver, each independently enableable, with three-state outputs when disabled.

 

Operating from a single 5V supply (4.75V to 5.25V), the ADM485AR consumes only 2.2mA typical supply current. It supports half duplex communication at data rates up to 5Mbps. The driver propagation delay is 10 ns typical, and the receiver propagation delay is 15 ns typical. The receiver hysteresis is 70 mV, and the bus common-mode range spans -7V to +12V.

 

The transceiver is housed in a surface-mount 8-SOIC package (0.154", 3.90mm width) and operates over an industrial temperature range of -40°C to +85°C. It includes thermal shutdown protection and short-circuit protection, making it suitable for robust industrial environments. Typical applications include low power RS-485 systems, DTE/DCE interfaces, packet switching, local area networks, and data multiplexers.
