ADM2483BRWZ-REEL

The ADM2483BRWZ-REEL from Analog Devices is an integrated, galvanically isolated differential bus transceiver designed for bidirectional data communication on balanced, multipoint bus transmission lines. It complies with ANSI TIA/EIA RS-485-A and ISO 8482 standards.

This digital isolator operates at a data rate of 500 kbps and provides 2500 Vrms of isolation. It features 3 channels and supports RS422 and RS485 interfaces. The device is suitable for 5 V or 3 V operations on the logic side and a 5 V supply on the bus side. Its slew-rate-limited driver outputs reduce reflections, and the high common-mode transient immunity of over 25 kV/µs ensures robust performance.

The ADM2483BRWZ-REEL is designed for low power operation, consuming a maximum of 2.5 mA. It is available in a 16-SOIC package and is suitable for surface mount applications. The operating temperature range is -40°C to +85°C, making it appropriate for various industrial and communication network applications.

Key features include true fail-safe receiver inputs, chatter-free power-up/power-down protection, and thermal shutdown protection. The device allows for up to 256 nodes on the bus, supporting multipoint data transmission systems.
