ADN4620BRIZ

Overview

The ADN4620BRIZ is a dual-channel LVDS digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 1.7V to 1.9V and 3V to 3.6V, providing an isolation voltage of 7500Vrms. The device supports data rates up to 2.5Gbps with a common-mode transient immunity of 35kV/µs. Propagation delays are typically 2.8ns maximum, with rise and fall times around 180ps. It functions in temperatures from -40°C to +125°C and is housed in a 16-SOIC package.

Feature Summary

• Integrates two unidirectional signal channels using on-chip transformer-based magnetic coupling for robust isolation.
• Supports high-speed LVDS signaling with data rates reaching 2.5Gbps for efficient serial communication.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Operates without requiring isolated power supplies, simplifying system design and reducing component count.

Applications

• High-speed serial communication interfaces requiring galvanic isolation
• Industrial automation systems with significant ground potential differences
• Medical equipment needing reinforced electrical isolation for safety
• Automotive electronics operating in high-noise electromagnetic environments

Procurement Notes

Verify the specific suffix BRIZ confirms the tape-and-reel packaging format and RoHS compliance status before ordering. Confirm that the 16-SOIC footprint matches your PCB layout constraints. Ensure the 7500Vrms isolation rating meets your application's safety standards. Check current availability as distribution may vary by region.

Selection Notes

Select this component when dual-channel LVDS isolation is required at speeds up to 2.5Gbps. Consider the 7500Vrms isolation barrier for high-voltage separation needs. Evaluate the 35kV/µs CMTI for noise immunity requirements. Compare against single-channel or quad-channel variants if channel count differs from project specifications.

Part Context

This part belongs to the ADN4620 series of iCoupler digital isolators. It complements other devices like the ADN4621 (quad channel) and evaluation boards such as EVAL-ADN4620EBZ. The series leverages silicon dioxide insulation technology for reliable performance across industrial temperature ranges.
