ADN4652BRWZ

Overview

The ADN4652BRWZ is a dual-channel LVDS digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation voltage with a minimum common-mode transient immunity of 25kV/µs. The device supports data rates up to 600Mbps and operates within a supply voltage range of 2.375V to 2.625V. It features unidirectional signal transmission across two channels, with maximum propagation delays of 4.5ns for both high-to-low and low-to-high transitions. Typical rise and fall times are 0.35ns. The component is housed in a 20-SOIC package and functions reliably within an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates dual independent LVDS channels for bidirectional data-plane isolation without requiring isolated power supplies.
• Employs on-chip transformer-based magnetic coupling to achieve high-voltage isolation with superior common-mode transient immunity.
• Supports high-speed data transmission at rates up to 600Mbps with minimal propagation delay variations.

Applications

• Isolated analogue front-end (AFE) circuits in industrial measurement systems
• Data-plane isolation for communication interfaces in motor control drives
• High-speed clock and data link isolation in energy metering applications

Procurement Notes

Verify the specific suffix BRWZ confirms the SOIC-20 wide body package and tube packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements during storage and handling. Ensure the ordering part number matches the exact channel count and isolation rating specifications required by the design.

Selection Notes

Select this component when dual-channel LVDS isolation is required with high common-mode transient immunity. Compare against ADN4650 and ADN4651 variants based on specific channel directionality needs. Ensure the 2.375V to 2.625V supply voltage range aligns with the system's power architecture. Validate that the 20-SOIC footprint fits the PCB layout constraints.

Part Context

This device belongs to the ADN4650/ADN4651/ADN4652 family of dual-channel LVDS isolators from Analog Devices. These components share similar core technologies but differ in channel configurations and isolation ratings. The ADN4652 specifically offers symmetric dual-channel isolation suitable for complex data transfer scenarios requiring robust noise rejection.

Replacement Considerations

Direct substitutes include ADN4652BRSZ for SSOP packaging or ADN4651BRWZ if channel directionality differs. Verify pinout compatibility and electrical parameters before substitution.
