ADN4656BRWZ

Overview

The ADN4656BRWZ is a dual-channel digital isolator utilizing magnetic coupling technology to provide galvanic isolation for high-speed data links. It supports unidirectional signal transmission at data rates up to 1.25 Gb/s with a propagation delay of 4 ns and rise/fall times of 350 ps. The device operates within a supply voltage range of 2.375 V to 3.6 V, drawing a typical operating current of 58 mA. It features a 5000 Vrms insulation voltage rating and a common-mode transient immunity of 25 kV/µs. Designed for robust performance, it functions across an extended temperature range from -40°C to +125°C and is housed in a 20-lead SOIC package.

Feature Summary

• Provides high-speed bidirectional data isolation using magnetic coupling technology for LVDS signals.
• Ensures system safety with a 5000 Vrms insulation rating and high common-mode transient immunity.
• Delivers precise timing characteristics with low propagation delay and fast edge rates for gigabit applications.

Applications

• Analog front-end isolation in industrial measurement systems
• Isolation for high-speed video and imaging data links
• Clock and data link isolation in communication equipment

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with required insulation ratings and thermal management solutions for the target application environment. Confirm availability status through authorized distributors as supply conditions may vary.

Selection Notes

Select this component when high-speed LVDS isolation is required with stringent safety standards. Consider the 20-lead SOIC footprint for PCB layout constraints. Evaluate power consumption requirements against the 58 mA typical current draw. Verify that the 5000 Vrms isolation level meets the specific regulatory requirements of the end application.

Part Context

This part belongs to the ADN4656 series of digital isolators from Analog Devices. The series utilizes proprietary magnetic coupling technology to replace traditional optocouplers in high-speed applications. The BRWZ suffix specifically denotes the SOIC-20 wide body package variant within this family.

Replacement Considerations
