ADUM6420ABRNZ3-RL

Overview

The ADUM6420ABRNZ3-RL is a quad-channel digital isolator from Analog Devices, utilizing isoPower technology to provide galvanic isolation up to 5 kV. It features four data channels with a 4:0 configuration and operates at a data rate of 100 Mb/s. The device supports a supply voltage range of 3 V to 3.6 V and draws an operating current of 190 mA. Packaged in a SOIC-28 surface-mount format, it ensures magnetic coupling isolation for robust signal transmission.

Feature Summary

• Integrates four independent data channels with a unidirectional 4:0 configuration for efficient signal routing.
• Employs isoPower technology to combine high-voltage isolation with integrated DC-to-DC conversion capabilities.
• Utilizes magnetic coupling isolation to achieve reliable galvanic separation between circuit domains.

Applications

• Industrial communication interfaces requiring multi-channel isolation
• Medical equipment signal processing circuits
• Automotive electronic control unit interconnects

Procurement Notes

Verify the specific suffix '3' against official datasheets to confirm the 4:0 channel configuration and 3.3V operation parameters. Confirm package type is SOIC-28 and check RoHS compliance status directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when four isolated output channels are required without corresponding input channels on the secondary side. Ensure the system design accommodates the 190 mA operating current and 3.6 V maximum supply voltage constraints inherent to the isoPower architecture.

Part Context

This part belongs to the ADuM family of digital isolators, specifically designed for applications demanding high reliability and low EMI. It integrates power conversion within the isolation barrier, reducing external component count compared to discrete solutions.

Replacement Considerations

Check ADUM6420 variants with different suffixes for alternative channel configurations or voltage levels. Verify pin compatibility and thermal performance if substituting with other quad-channel isolators from the same manufacturer series.
