ADN4624BRNZ-RL

Overview

The ADN4624BRNZ-RL is a quad-channel digital isolator from Analog Devices, designed for high-speed LVDS signal transmission. It features a 4+0 channel configuration supporting data rates up to 2.5 Gbps with a total bandwidth of 10 Gbps across all channels. The device provides galvanic isolation with an insulation voltage of 5700 Vrms and complies with TIA/EIA-644-A LVDS signal levels. It operates on dual power supplies ranging from 1.7 V to 1.9 V and 3 V to 3.6 V, consuming approximately 140 mA. Key performance metrics include a typical propagation delay of 2.15 ns, rise/fall times of 180 ps, and common-mode transient immunity of 100 kV/µs. Packaged in a 28-lead SOIC_W_FP.

Feature Summary

• Provides galvanic isolation for four independent LVDS channels with unidirectional signal flow.
• Supports high-speed data transmission up to 2.5 Gbps per channel with low jitter characteristics.
• Features robust electromagnetic compatibility including ±8 kV IEC 61000-4-2 ESD protection across the isolation barrier.
• Utilizes a wide-body package design to ensure adequate creepage and clearance distances for safety compliance.

Applications

• High-speed serial communication interfaces requiring electrical isolation
• Industrial automation systems with noisy electrical environments
• Medical equipment requiring certified isolation barriers
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm that the SOIC_W_FP package matches the target PCB footprint, as pin pitch differs from standard SOIC. Ensure supply chain partners provide valid RoHS compliance documentation. Check for pending certification statuses such as IEC/EN/CSA 62368-1 or IEC/CSA 60601-1 if regulatory approval is required for the final application. Validate moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when four isolated LVDS channels are required at data rates up to 2.5 Gbps. It is suitable for applications needing high common-mode transient immunity and low propagation delay. Consider the 28-lead wide-body package for improved thermal and electrical performance compared to smaller packages. Ensure the system design supports the specified dual-voltage power supply requirements for optimal operation.

Part Context

This part belongs to the ADN462x series of digital isolators from Analog Devices. It complements other variants like the ADN4622 (2+2 channels) and ADN4621 (dual bidirectional). The series utilizes proprietary capacitive coupling technology to achieve high-speed isolation without magnetic components. It is part of the broader interface IC portfolio designed for robust signal integrity in demanding environments.

Replacement Considerations

Direct functional substitutes within the same family include ADN4622BRNZ-RL for a 2+2 channel configuration. For single-ended LVDS applications, consider ADN4621BRIZ. Verify package compatibility and pinout alignment before substitution. Performance parameters such as propagation delay and isolation voltage should be compared against the original specifications to ensure system integrity.
