ADN4624BCPZ

Overview

The ADN4624BCPZ is a quad-channel digital isolator from Analog Devices, designed for high-speed LVDS signal transmission. 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 5700 Vrms isolation voltage per UL 1577 standards and supports supply voltages ranging from 1.7 V to 3.6 V. It features ±8 kV IEC 61000-4-2 ESD protection across the isolation barrier and a common-mode transient immunity of 100 kV/µs. Packaged in a 32-lead LFCSP, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides four isolated LVDS channels with low jitter performance for high-speed data integrity
• Delivers robust insulation with 5700 Vrms withstand voltage and high common-mode transient immunity
• Includes integrated ESD protection rated at ±8 kV across the isolation barrier
• Complies with TIA/EIA-644-A LVDS signal level specifications

Applications

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

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm package marking matches ADN4624BCPZ and check datasheet revisions for specific lot traceability requirements. Ensure storage conditions comply with moisture sensitivity levels indicated on the label. Validate that the received units match the ordered configuration before integration into production lines.

Selection Notes

Select this component when four independent LVDS channels are required within a single isolated boundary. It is suitable for designs needing high bandwidth up to 10 Gbps total across all channels. Consider the 32-lead LFCSP package for space-constrained PCB layouts. Ensure the application environment stays within the specified operating temperature range and supply voltage limits for optimal performance.

Part Context

This part belongs to the ADN4624 series of gigabit isolators manufactured by Analog Devices. It is distinct from the ADN4622, which offers a 2+2 channel configuration instead of 4+0. The device utilizes capacitive coupling technology for signal transmission across the isolation barrier. It is part of Analog Devices' broader portfolio of interface and isolation integrated circuits designed for demanding industrial and communication applications.

Replacement Considerations

The ADN4622BRNZ-RL is a related quad-channel variant but features a 2+2 channel configuration rather than 4+0. Verify pin compatibility and functional differences before substitution. No other direct cross-references are confirmed in public documentation.
