ADN4652BRWZ-RL7

Overview

The ADN4652BRWZ-RL7 is a dual-channel LVDS digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It provides galvanic isolation with a rated voltage of 5000 Vrms and supports data rates up to 600 Mbps. The device features a common mode transient immunity (CMTI) of 25 kV/µs, ensuring reliable signal transmission in noisy environments. It operates on a single power supply ranging from 2.375 V to 2.625 V and includes integrated low-power oscillators for both channels. The component is housed in a 20-SOIC package and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates two independent bidirectional channels for high-speed LVDS signal isolation
• Employs iCoupler magnetic coupling technology to eliminate the need for external transformers
• Features low propagation delay and jitter for precise timing applications
• Includes integrated low-power oscillators to simplify system design

Applications

• High-speed serial communication interfaces requiring galvanic isolation
• Industrial automation systems with noisy electrical environments
• Medical equipment requiring safety isolation between circuits
• Automotive electronics systems needing robust signal integrity

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm the SOIC-20 package width matches your PCB footprint requirements. Ensure the 2.375 V to 2.625 V supply voltage aligns with your system's power rails. Check RoHS compliance status if required by your manufacturing standards. Validate the 5000 Vrms isolation rating against your application's safety regulations.

Selection Notes

Select this component when dual-channel LVDS isolation is required at speeds up to 600 Mbps. Consider the 25 kV/µs CMTI rating for environments with high electromagnetic interference. The narrow supply voltage range necessitates careful power management design. Compare pinout compatibility with existing designs if replacing older isolator models. Evaluate thermal performance within the specified -40°C to +125°C operating range.

Part Context

This part belongs to the ADN465x series of digital isolators from Analog Devices. It shares architectural similarities with other iCoupler devices but is optimized for LVDS interfaces. The series offers various channel counts and isolation voltages to suit different application needs. The BRWZ suffix denotes the wide-body SOIC package variant suitable for higher isolation creepage distances.

Replacement Considerations

Direct substitutes include ADN4652BRWZ without the reel suffix for tape-and-reel equivalent functionality. ADN4654BRWZ-RL7 offers four channels instead of two for expanded I/O needs. ADN4650BRWZ-RL7 provides single-channel isolation for simpler interface requirements. Verify pin-to-pin compatibility before substituting any alternative model.
