ADUM6422ABRNZ5-RL

Overview

The ADUM6422ABRNZ5-RL is an isoPower device integrating a quad-channel digital isolator with an isolated DC-to-DC converter. It provides 5kV isolation and supports data rates up to 100 Mbps. The integrated converter accepts input voltages from 1.7 V to 5.5 V, delivering regulated outputs of 3.3 V or 5 V at 100 mA. Operating within a temperature range of -40°C to +125°C, it utilizes magnetic coupling technology in a 28-pin SOIC package.

Feature Summary

• Integrates four bidirectional digital channels with an isolated power supply
• Provides robust 5000 Vrms insulation barrier for safety compliance
• Features low electromagnetic interference design for signal integrity
• Supports flexible output voltage configurations via external components

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced isolation barriers
• Automotive electronics operating in high-noise environments
• Data acquisition modules with mixed-signal interfaces

Procurement Notes

Verify the specific suffix '5' indicates the tape-and-reel packaging configuration. Confirm that the A-grade designation meets your reliability requirements. Check current availability status as distribution may be limited. Ensure compatibility with your board layout constraints for the 28-pin SOIC package. Validate thermal management needs for the specified power dissipation levels.

Selection Notes

Select this component when both high-speed data isolation and compact power delivery are required. It eliminates the need for separate isolated power supplies. Consider the 100 Mbps data rate against your system bandwidth. Evaluate the 100 mA output current capability against load demands. Assess the 28-pin footprint against available PCB space.

Part Context

This part belongs to the ADuM64xx family of isoPower devices. These components combine iCoupler technology with integrated converters. They simplify designs by reducing component count and board area. The family targets applications demanding high reliability and small form factors.

Replacement Considerations

Check for ADUM6422 variants with different packaging options. Verify if ADUM6402 series parts meet lower speed requirements. Confirm pinout compatibility before substituting other isolators.
