ADN4650BRWZ-RL7

Overview

The ADN4650BRWZ-RL7 is a dual-channel LVDS digital isolator from Analog Devices, utilizing magnetic coupling technology. It operates with a supply voltage range of 2.375 V to 2.625 V and supports data rates up to 600 Mbps. The device provides 5000 Vrms isolation voltage and a common-mode transient immunity of 25 kV/µs. Propagation delays are typically 4 ns, with rise and fall times of 0.35 ns. It features two channels in an unidirectional configuration within a 20-SOIC package, operating between -40°C and +125°C.

Feature Summary

• Integrates dual-channel LVDS isolation using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Provides robust electrical isolation with 5000 Vrms rating and high common-mode transient immunity of 25 kV/µs.
• Delivers low propagation delay and fast edge rates suitable for precise timing applications.
• Operates on a single low-voltage power supply without requiring isolated power domains.

Applications

• Motor control systems requiring galvanic isolation between controller and drive stages.
• Industrial communication interfaces such as RS-485 or CAN transceivers.
• Medical equipment needing safety-certified signal isolation.
• Power electronics monitoring circuits.

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the 20-SOIC footprint matches the PCB design. Check humidity sensitivity levels for proper storage and handling requirements during assembly.

Selection Notes

Select this component for applications requiring LVDS interface isolation with high speed and reliability. Compare against ADN4651 and ADN4652 variants if bidirectional or different channel counts are needed. Ensure the 2.375 V to 2.625 V supply range aligns with the system's logic levels. Verify thermal performance within the -40°C to +125°C operating range.

Part Context

This part belongs to the ADN4650 series of dual-channel LVDS isolators. It is designed to replace optocouplers in high-speed digital isolation applications. The series offers improved performance in terms of speed, power consumption, and size compared to traditional optical isolation technologies.

Replacement Considerations

Direct substitutes include ADN4650BRWZ and ADN4650BRSZ. Consider ADN4651BRWZ for bidirectional functionality. Verify pinout compatibility and package dimensions before substitution.
