Digital Isolators

ADM2486BRW Description

The ADM2486BRW from Analog Devices Inc. is a high-performance, 3-channel digital isolator integrating RS422/RS485 transceivers with 2.5kVrms isolation using magnetic coupling (iCoupler® technology). Designed for robust communication in noisy environments, it supports bidirectional data transmission at speeds up to 20Mbps with low propagation delay (55ns max). The device operates on 3V or 5V supplies, making it versatile for mixed-voltage systems. Though now obsolete, it remains a reliable choice for legacy designs requiring high common-mode transient immunity (25kV/µs) and minimal pulse width distortion (5ns max). Packaged in a 16-pin SOIC, it is suited for surface-mount applications.

ADM2486BRW Features

• Isolation & Safety: 2500Vrms reinforced isolation meets stringent industrial standards.
• High-Speed Performance: 20Mbps data rate with 5ns rise/fall times for efficient signal integrity.
• Robust Noise Immunity: 25kV/µs CMTI ensures reliability in electrically harsh environments.
• Low Power & Versatility: Dual-supply operation (3V/5V) reduces system complexity.
• Compact Integration: Combines 3 bidirectional channels (2 inputs, 1 output) in a 16-SOIC package.
• Industry Compliance: EAR99 and HTSUS 8542.39.0001 listed for global compatibility.

ADM2486BRW Applications

• Industrial Networks: Isolated RS485/RS422 interfaces for PLCs, motor drives, and factory automation.
• Medical Equipment: Noise-resistant data links in patient monitoring or diagnostic devices.
• Power Systems: Isolated communication in inverters, smart meters, and renewable energy converters.
• Legacy Upgrades: Retrofitting older systems requiring high-speed, isolated serial communication.

Conclusion of ADM2486BRW

The ADM2486BRW excels in applications demanding high-speed, noise-immune isolation with minimal signal distortion. Its magnetic coupling technology and bidirectional channels simplify design while ensuring robustness. Although obsolete, its proven performance in industrial, medical, and energy systems makes it a enduring solution for engineers prioritizing reliability in isolated data transmission. For new designs, consider Analog Devices' newer iCoupler® alternatives with enhanced features.
