The ADM2483BRWZ from Analog Devices is an integrated, galvanically isolated differential bus transceiver. It is designed for bidirectional data communication on balanced, multipoint bus transmission lines, complying with ANSI EIA/TIA-485-A and ISO 8482: 1987(E).
Key electrical specifications include a data rate of 500 kbps, a high common-mode transient immunity of >25 kV/µs, and 2500Vrms isolation. The device supports 3 channels and operates bidirectionally. It is suitable for 5 V or 3 V operations on the logic side and uses a 5 V supply on the bus side.
This transceiver is housed in a 16-SOIC package and is designed for surface mount applications. The operating temperature range is -40°C to +85°C, making it suitable for various industrial environments. Features like slew-rate limited driver outputs and fail-safe receiver inputs enhance its robustness in multipoint data transmission systems.
Applications include low power RS-485/RS-422 networks, isolated interfaces, building control networks, and multipoint data transmission systems. The device offers thermal shutdown protection and supports up to 256 nodes on the bus.
