ADUM6423ABRNZ5-RL

Overview

The ADUM6423ABRNZ5-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It provides four data channels with a 1:3 input-output configuration and supports data rates up to 100 Mb/s. The device operates within a supply voltage range of 4.5 V to 5.5 V and offers an insulation voltage of 500 Vrms. Key electrical parameters include a propagation delay of 10 ns, pulse width distortion of 1 ns, and a typical rise/fall time of 2.5 ns. It functions reliably across an operating temperature range of -40°C to +125°C and is housed in a SOIC-28 surface-mount package.

Feature Summary

• Integrates an isolated DC-to-DC converter for simplified power delivery across the isolation barrier
• Provides low electromagnetic interference (EMI) performance suitable for noise-sensitive applications
• Features high common-mode transient immunity for reliable signal transmission in harsh environments

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing galvanic isolation for safety compliance
• Data acquisition modules interfacing with high-voltage sensors

Procurement Notes

Verify the specific suffix '5' and '-RL' packaging designation against the manufacturer's current datasheet to ensure compatibility with your reel quantity requirements. Confirm that the SOIC-28 footprint matches your PCB layout constraints. Check for any recent product change notices regarding pinout or electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a quad-channel isolator with integrated power conversion is required to reduce external component count. It is suitable for designs needing 100 Mb/s data throughput with moderate propagation delay. Consider the thermal dissipation capabilities of the SOIC-28 package relative to your system's power budget and ambient temperature conditions.

Part Context

This part belongs to the ADuM642xA family of quad-channel digital isolators. These devices are designed to replace traditional transformer and optocoupler-based solutions in space-constrained applications. The family emphasizes low EMI and high reliability, making it a standard choice for modern interface ICs requiring galvanic separation between logic domains.
