ADUM6421ABRNZ5-RL

Overview

The ADUM6421ABRNZ5-RL is a quad-channel digital isolator with an integrated isoPower DC-to-DC converter, manufactured by Analog Devices. It features a 3:1 data direction configuration and operates with a 5V output. The device utilizes magnetic coupling for isolation, providing a 5kV insulation voltage rating. It supports a switching frequency of 180 MHz and delivers an output current of 100 mA per channel. The component is housed in a SOIC-28 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates four isolated digital channels with a built-in DC-to-DC power converter
• Provides low electromagnetic interference (EMI) performance
• Offers high insulation voltage capability for robust signal isolation

Applications

• RS-232 transceivers
• Power supply gate drives
• Sensor interfaces

Procurement Notes

Verify availability status as the part may be subject to limited supply or factory special orders. Confirm that the specific suffix indicates the correct data direction and pinout configuration required for your design. Ensure compliance with RoHS standards and check for any regional shipping restrictions before finalizing procurement plans.

Selection Notes

Select this component when a compact solution combining isolated data transmission and power delivery is required. The 3:1 data direction suits applications where three signals flow one way and one returns. Consider the SOIC-28 footprint and thermal management capabilities given the integrated converter. Verify that the 100 mA output current meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the ADuM6421 family of quad-channel isolators with integrated power converters. It represents a specialized variant designed for specific data directionality and voltage levels. The series is known for combining magnetic isolation technology with on-chip power generation to simplify system design and reduce external component count.

Replacement Considerations

Check for other variants within the ADuM6421 family that may offer different data directions or voltage outputs. Verify pin compatibility if substituting with similar isoPower devices from Analog Devices.
