ADUM3480BRSZ-RL7 - Isolated Precision Half-Duplex RS-485/RS-422 Transceiver

The ADUM3480BRSZ-RL7 is a cutting-edge communication component from Analog Devices Inc., designed to offer robust data transmission in industrial environments. This device is a precision-engineered isolated half-duplex RS-485/RS-422 transceiver that allows for bidirectional communication on balanced transmission lines. It is part of the iCoupler® family, which incorporates Analog Devices' proprietary digital isolation technology to provide both signal and power isolation in a single package.

Featuring a wide supply voltage range of 3.0 V to 5.5 V, the ADUM3480BRSZ-RL7 is versatile and can be used in various applications, including isolated RS-485/RS-422 communication in harsh electrical environments. The transceiver supports data rates up to 25 Mbps, making it suitable for high-speed communication requirements. Its integrated isolated dc-to-dc converter eliminates the need for a separate isolated power supply, simplifying design and reducing board space.

The device comes in a compact 16-lead SOIC package with increased creepage for enhanced insulation and reliability. The increased isolation is essential for meeting stringent industrial safety requirements. It is characterized for operation over the wide temperature range of -40°C to +105°C, ensuring reliable performance even in extreme conditions.

Key features of the ADUM3480BRSZ-RL7 include true fail-safe receiver inputs, which ensure a known state in the absence of an input signal, and a hot-swap capability that allows nodes to be connected or disconnected without affecting the data bus. The transceiver also offers a low power shutdown mode, reducing power consumption when the device is not in active use.

With its reinforced insulation, the ADUM3480BRSZ-RL7 provides a high level of protection against electrical hazards, making it an ideal choice for applications requiring both signal integrity and safety. Its robust design and advanced features make it well-suited for industrial networks, motor control, and other applications requiring reliable data communication in electrically noisy environments.

Overall, the ADUM3480BRSZ-RL7 from Analog Devices Inc. represents a state-of-the-art solution for safe, efficient, and high-speed data transmission in industrial applications.
