ADN4624BRNZ

Overview

The ADN4624BRNZ is a quad-channel LVDS digital isolator manufactured by Analog Devices Inc. It operates at data rates up to 2.5 Gbps with a typical propagation delay of 2.15 ns and rise/fall times of 180 ps. The device provides galvanic isolation with an insulation voltage of 5700 Vrms. It supports dual power supplies ranging from 1.7 V to 1.9 V and 3 V to 3.6 V, consuming 140 mA of operating current. Packaged in a 28-lead SOIC_W_FP, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides unidirectional signal transmission across four independent channels using LVDS signaling compliant with TIA/EIA-644-A standards.
• Delivers high common-mode transient immunity of 100 kV/µs typical for robust noise rejection in electrically noisy environments.
• Features low jitter performance with 0.82 ps rms random and 40 ps total peak values to maintain signal integrity at high speeds.
• Includes ±8 kV IEC 61000-4-2 electrostatic discharge protection across the isolation barrier.

Applications

• High-speed serial communication interfaces requiring galvanic isolation
• Industrial automation systems with significant ground potential differences
• Medical equipment requiring reinforced isolation barriers
• Test and measurement instrumentation such as oscilloscopes and signal generators

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm package marking matches the SOIC-28 specification and check for valid RoHS compliance documentation. Ensure storage conditions account for humidity sensitivity before soldering. Validate that the specific order quantity aligns with factory tube packaging requirements rather than standard retail units.

Selection Notes

Select this component when bidirectional communication is not required, as it offers only unidirectional channels. Compare against the ADN4622 if a 2+2 channel configuration is preferred over the 4+0 layout. Consider the EVAL-ADN4624EB1Z evaluation board for initial circuit validation. Ensure the design accommodates the 28-lead wide-body package dimensions and thermal dissipation needs of 2.74 W.

Part Context

This part belongs to the ADN462x family of gigabit LVDS isolators designed for high-bandwidth applications. It complements other variants like the ADN4620 and ADN4621 which offer different channel counts and isolation voltages. The series utilizes proprietary capacitive coupling technology to achieve high data rates while maintaining small form factors suitable for dense PCB layouts.

Replacement Considerations

The ADN4624BRIZ-RL serves as the reel-pack equivalent of this tube-packed component. No direct cross-brand substitutes are confirmed in public documentation. Verify pinout compatibility if considering alternative manufacturers' LVDS isolators.
