ADM485EARZ Description

Short technical summary and product information.

The ADM485EARZ from Analog Devices is a 5V, low-power, half-duplex data transceiver compliant with TIA/EIA RS-485 and RS-422 standards. It features ±15 kV ESD protection on its RS-485 I/O pins and supports data rates up to 2.5 Mbps. The transceiver is designed for multipoint bus transmission lines and includes features like thermal shutdown and short-circuit protection to prevent excessive power dissipation.

 

This device operates within a voltage range of 4.75V to 5.25V and is specified for industrial temperature ranges from -40°C to 85°C. The ADM485EARZ is housed in an 8-lead SOIC package, suitable for surface mount applications. Its receiver input impedance allows for up to 32 transceivers on a bus, making it suitable for various industrial control, telecommunications, and instrumentation systems.

 

Key electrical characteristics include a common-mode input range of -7V to +12V and 70 mV of receiver hysteresis. The driver outputs are slew-rate limited to reduce electromagnetic interference (EMI) and data errors caused by bus reflections.
