ADM1490EBRZ-REEL7: High-Speed, Half-Duplex, iCoupler Isolated RS-485 Transceiver

The ADM1490EBRZ-REEL7 is a robust, high-speed, half-duplex RS-485/RS-422 transceiver designed by Analog Devices Inc., which integrates iCoupler® technology to provide isolation between the data line and logic level circuitry. This transceiver is engineered to operate in demanding environments, making it suitable for industrial field bus communications and data networks requiring high-speed, bidirectional data communication over long distances or in noisy environments.

Key Features:

• Integrated Isolation: The device features iCoupler technology, which provides 2500 V RMS isolation for 1 minute between the bus line and the logic side, enhancing safety and reliability in harsh electrical environments.
• High Data Rates: It supports data rates up to 16 Mbps, enabling high-speed data transmission for time-critical applications.
• Half-Duplex Communication: The ADM1490EBRZ-REEL7 is designed for half-duplex communication, allowing for bidirectional communication over a single pair of wires, reducing the complexity and cost of the network.
• Thermal Shutdown Protection: The device includes thermal shutdown protection, which prevents damage to the transceiver in the event of excessive power dissipation.
• Fail-Safe Receiver: The receiver has a fail-safe feature that ensures a known state if the inputs are open or shorted, or if the differential input voltage is 0 V.
• Extended Temperature Range: It operates over an industrial temperature range of -40°C to +85°C, ensuring reliable performance in extreme conditions.
• ESD Protection: The transceiver provides ±8 kV contact discharge protection on the transceiver bus pins to enhance robustness and longevity.
• RoHS Compliant: The device is compliant with RoHS standards, minimizing the environmental impact by restricting the use of certain hazardous substances.

Applications:

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