ADM2483BRWZ Isolated RS-485 Transceiver

The ADM2483BRWZ is a robust, high-speed, fully isolated RS-485 transceiver designed by Analog Devices Inc., a leader in high-performance semiconductors. This transceiver is engineered to provide reliable data communications on multipoint bus transmission lines, making it an ideal choice for industrial and commercial applications where isolation and robustness are essential.

Featuring an integrated isolated dc-to-dc power supply, the ADM2483BRWZ eliminates the need for an external isolation component, thus simplifying design and reducing board space. It operates over a wide supply voltage range from 3.0 V to 5.5 V, which allows for flexible integration into various systems. The device is capable of data rates up to 500 kbps, making it suitable for high-speed data transfer requirements.

The ADM2483BRWZ comes in a wide-body, 16-lead SOIC package, providing 2.5 kV RMS of isolation for 1 minute per UL 1577. This level of isolation ensures that the data lines are protected from high voltage spikes and ground loops, which can be common in harsh industrial environments. The transceiver is also characterized for operation over the industrial temperature range of -40°C to +85°C, ensuring reliable performance under extreme conditions.

With true fail-safe receiver inputs, the ADM2483BRWZ guarantees a logic high receiver output when the inputs are open or shorted, or when they are connected to a terminated transmission line with all drivers disabled. This feature significantly enhances the reliability of the communication system.

Additional features of the ADM2483BRWZ include thermal shutdown protection, which prevents damage to the device in the event of excessive power dissipation, and a driver slew rate limited to reduce EMI and reflections, allowing for error-free data transmission even over long cable runs.

Whether it's for industrial control, factory automation, or any application requiring robust data communication with isolation, the ADM2483BRWZ from Analog Devices Inc. offers a high-performance, reliable solution that designers can trust.
