ADM2491EBRWZ-REEL7 - Robust Isolated RS-485 Transceiver

The ADM2491EBRWZ-REEL7 is a high-performance, isolated RS-485 transceiver module designed by Analog Devices Inc. This device is engineered to provide reliable data communications on multipoint bus transmission lines. It is a perfect solution for industrial and commercial applications where isolation and robustness are critical requirements.

The ADM2491EBRWZ-REEL7 comes in a wide-body, 16-lead SOIC package and is part of a tape and reel, indicated by the suffix '-REEL7'. This packaging ensures compatibility with automated assembly processes, making it a convenient option for mass production.

Key Features:

• Integrated Isolation: The device incorporates Analog Devices' iCoupler® technology to provide 2.5 kV RMS isolation, which protects against high voltage spikes and ground loops, ensuring signal integrity and system safety.
• High Data Rates: Capable of supporting data rates up to 500 kbps, the ADM2491EBRWZ-REEL7 is suitable for high-speed data transmission while maintaining precise signal timing.
• Thermal Shutdown Protection: The transceiver includes a thermal shutdown feature that protects the device from damage due to excessive power dissipation.
• ESD Protection: With high ESD protection levels of ±15 kV on the RS-485 input/output lines, the device can withstand harsh electrical environments and reduce system failures.
• Half-Duplex Operation: The ADM2491EBRWZ-REEL7 supports half-duplex communication, allowing bidirectional communication over a single pair of wires, which helps to minimize the number of cables and reduce costs.
• Fail-Safe Receiver: The receiver remains in a high impedance state when the bus is idle, shorted, or open, which prevents false data transmission.
• Wide Operating Temperature Range: It operates effectively across an industrial temperature range from -40°C to +85°C, making it reliable in extreme conditions.

Applications:

The ADM2491EBRWZ-REEL7 is ideal for various applications, including but not limited to:

• Industrial field buses
• Building automation
• Factory automation
• Process control systems

With its combination of features, the ADM2491EBRWZ-REEL7 by Analog Devices Inc. is a robust solution for systems that require reliable data transmission with electrical isolation in demanding environments.
