Description

ADM2587EBRWZ Isolated RS-485 Transceiver by Analog Devices Inc.

The ADM2587EBRWZ from Analog Devices Inc. is a robust, high-speed, fully isolated RS-485/RS-422 transceiver designed to provide reliable data communication with enhanced safety and noise immunity. This component is essential for applications requiring isolation due to differences in ground potential or noisy environments. The ADM2587EBRWZ is part of the broad portfolio of interface components from Analog Devices that are known for their reliability and performance.

This transceiver integrates Analog Devices’ iCoupler® technology to combine a 3-channel isolator, a three-state differential line driver, a differential input receiver, and Analog Devices’ isoPower® DC-to-DC converter into a single package. The result is a complete isolated RS-485 solution that does not require any external components for isolation, which simplifies PCB design and enhances system reliability.

Key Features:

• Integrated Isolation:With 2.5kV RMS isolation rating for the data transceiver and power, the ADM2587EBRWZ ensures safe operation even in harsh electrical environments.
• High Data Rates:It supports data rates up to 500 kbps, making it suitable for a variety of high-speed applications.
• Thermal Shutdown Protection:The device includes thermal shutdown protection, which prevents damage from overheating.
• Wide Operating Temperature Range:It operates over a wide temperature range from -40°C to +85°C, ensuring reliability across diverse operating conditions.
• Industry Standard Compliance:The transceiver meets the EIA/TIA-485 standard for balanced data transmission and offers robust ESD protection.
• Reduced Power Consumption:The integrated isoPower technology provides efficient DC-to-DC conversion, reducing power consumption and eliminating the need for a separate isolated power supply.
• Compact Package:Available in a wide body, 20-lead SOIC package, it conserves board space while still providing the necessary isolation.

The ADM2587EBRWZ is ideal for industrial fieldbus networks, factory automation, energy metering, and other applications where a reliable, isolated communication interface is critical. With its integrated design and proven performance, this transceiver simplifies design, reduces costs, and accelerates time-to-market for engineers and designers.
