ADM3485EARZ-REEL Description

Short technical summary and product information.

The ADM3485EARZ is a 3.3 V half-duplex transceiver from Analog Devices, designed for balanced data transmission on multipoint RS-485 and RS-422 buses. It contains one driver and one receiver (1/1) and supports data rates up to 12 Mbps.

 

The transceiver provides ±15 kV ESD protection on the RS-485 input/output pins and features a receiver open-circuit fail-safe design. It includes thermal shutdown and short-circuit protection, and driver outputs go high-impedance when disabled or powered off. The common-mode input range spans -7 V to +12 V, and the 12 kΩ receiver input impedance allows up to 32 transceivers on a bus. Receiver hysteresis is 50 mV typical.

 

Typical applications listed by the manufacturer include power/energy metering, telecommunications, EMI-sensitive systems, industrial control, and local area networks. The device is available in an 8-lead narrow SOIC package (8-SOIC, 0.154" body width) for surface-mount assembly, and operates over -40°C to +85°C.
