ADN4650BRWZ

Overview

The ADN4650BRWZ is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It supports LVDS signaling with a data rate of 600 Mbps and offers 5000 Vrms isolation voltage. The device operates on a supply voltage range of 2.375 V to 2.625 V, drawing 60 mA of operating current. It features a propagation delay of 4 ns and rise/fall times of 350 ps. Housed in a 20-SOIC package, it functions as a unidirectional buffer with two forward channels and zero reverse channels. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates iCoupler magnetic coupling technology for signal isolation without external transformers
• Supports high-speed LVDS interface communication at rates up to 600 Mbps
• Provides robust common-mode transient immunity for reliable operation in noisy environments

Applications

• Motor control systems requiring isolated gate drive signals
• Industrial automation interfaces needing high-speed data transmission across isolation barriers
• Medical equipment requiring galvanic isolation for patient safety compliance

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm packaging configuration, as variations exist between tube and reel formats. Confirm that the selected variant matches the required isolation voltage rating and channel directionality for the target application design. Ensure compatibility with the intended PCB footprint and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring bidirectional or unidirectional LVDS signal isolation with high speed. Compare channel configurations carefully, as other variants in the series may offer different input/output arrangements. Ensure the power supply voltage strictly adheres to the specified 2.375 V to 2.625 V range to maintain performance specifications and prevent device malfunction during operation.

Part Context

This part belongs to the ADN4650/ADN4651/ADN4652 family of dual-channel LVDS isolators from Analog Devices. These devices are designed to replace bulky optical couplers in high-speed applications. The BRWZ suffix specifically denotes the SOIC-20 package format. This family leverages silicon dioxide insulation layers to provide superior electrical isolation compared to traditional technologies.

Replacement Considerations

Direct substitutes include ADN4651BRWZ and ADN4652BRWZ from the same manufacturer. Verify pinout compatibility and channel directionality differences before swapping. Other manufacturers' LVDS isolators may require significant schematic and layout modifications due to differing control logic or power requirements.
