ADUM6422ABRNZ3-RL

Overview

The ADUM6422ABRNZ3-RL is a quad-channel digital isolator from Analog Devices, utilizing isoPower technology to integrate magnetic coupling isolation with on-chip power conversion. It features a 2:2 data channel configuration and operates at a data rate of 100 Mb/s. The device provides an insulation voltage of 5000 Vrms and functions within a supply voltage range of 3 V to 3.6 V. Key electrical parameters include a propagation delay of 10 ns and a pulse width distortion of 1 ns. It is housed in a SOIC-28 package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Integrates four isolated channels with dual-side DC/DC converters for simultaneous signal and power transmission
• Employs iCoupler magnetic coupling technology to achieve high insulation voltage without external transformers
• Designed for low electromagnetic interference (EMI) performance in high-speed digital communication systems

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment interfaces needing reinforced safety isolation
• Automotive electronics with high-voltage noise immunity requirements

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix '3' indicates the correct reel packaging variant. Check current availability status as supply may be restricted. Ensure compliance with RoHS directives and humidity sensitivity handling protocols during storage and assembly.

Selection Notes

Select this model when a 2:2 channel split is required alongside integrated power delivery. Compare against the ADUM6422ABRNZ5-RL if a 5V logic interface is preferred instead of 3.3V. Consider the ADUM6424ABRNZ5-RL if a 0:4 unidirectional configuration better suits the application topology. Evaluate thermal dissipation capabilities within the SOIC-28 package for the target environment.

Part Context

This component belongs to the ADuM642x family of isoPower digital isolators. It combines high-speed data isolation with efficient power management in a single compact package. The series is designed to simplify board layout by eliminating external isolation barriers and magnetics, reducing overall system size and complexity for industrial and medical applications.

Replacement Considerations

Direct substitutes include ADUM6422ABRNZ5-RL for 5V operation. For different channel configurations, consider ADUM6421AWBRNZ5-RL (3:1) or ADUM6424ABRNZ5-RL (0:4). Verify pin compatibility and voltage levels before substitution.
