ADUM6422ABRNZ5

Overview

The ADUM6422ABRNZ5 is a quad-channel digital isolator featuring an integrated isoPower isolated DC-to-DC converter. It provides 5kV isolation with low EMI characteristics and supports 100Mbps data rates. The device operates within a -40°C to +125°C temperature range, utilizing a SOIC-28 package. Key electrical parameters include a 1.7V to 5.5V input voltage range, 3.3V or 5V output options, 100mA output current, 14mA static current, and an 180MHz switching frequency.

Feature Summary

• Integrates a high-frequency isolated DC-to-DC converter for power delivery across the isolation barrier
• Provides robust signal isolation with high common-mode transient immunity
• Features low electromagnetic interference design for sensitive applications

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Automotive electronics with strict noise immunity requirements

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm lot traceability and RoHS compliance status prior to acquisition. Check for restricted supply conditions as availability may be limited. Ensure storage and handling procedures meet moisture sensitivity level requirements to prevent damage during assembly.

Selection Notes

Select this component when simultaneous power and data isolation are required in a compact form factor. Consider the 2:2 channel configuration for bidirectional communication needs. Evaluate the 100Mbps data rate against system timing constraints. Assess the integrated converter capability to simplify PCB layout by eliminating external isolation transformers.

Part Context

This part belongs to the ADUM642x family of isoPower isolators from Analog Devices. These devices combine digital isolation technology with integrated power conversion.
