ADUM2402BRWZ

Overview

The ADUM2402BRWZ is a quad-channel digital isolator utilizing Analog Devices iCoupler technology. It features four independent isolation channels with a 5000 Vrms isolation voltage and 10 Mbps data rate. The device operates on supply voltages ranging from 2.7 V to 5.5 V, supporting bidirectional communication and level translation. Key electrical parameters include a minimum common-mode transient immunity of 25 kV/µs, maximum propagation delay of 50 ns, and typical rise/fall times of 2.5 ns. It functions within an operating temperature range of -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Utilizes monolithic air core transformer technology for robust signal isolation without LEDs or photodiodes
• Provides low pulse width distortion and tight channel-to-channel matching for precise timing applications
• Incorporates a patented refresh feature to ensure DC correctness during power-up, power-down, and idle states

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety barriers
• Power management circuits for monitoring and control
• Data acquisition systems with mixed-signal environments

Procurement Notes

Verify the specific suffix (BRWZ) against the manufacturer's current ordering guide to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the datasheet revision date to confirm that all electrical characteristics align with your design specifications before finalizing procurement.

Selection Notes

Select this component when high-speed bidirectional communication is required across a 5000 Vrms barrier. It is suitable for applications demanding low power consumption compared to optocouplers. Consider the 16-SOIC footprint for PCB layout constraints. Verify that the 10 Mbps data rate meets system throughput needs and that the 2.7 V to 5.5 V supply range matches the logic levels on both sides of the isolation barrier.

Part Context

The ADUM2402BRWZ belongs to the ADuM240x family of quad-channel digital isolators. This series combines high-speed CMOS technology with iCoupler magnetic coupling to replace traditional optocouplers. The BRWZ suffix indicates a specific package and reel configuration within the broader ADUM2402 product line, which includes variants like ADUM2402ARWZ with different speed grades.

Replacement Considerations

ADUM2402ARWZ offers similar functionality but operates at a lower data rate of 1 Mbps. ADUM2401BRWZ provides three channels on one side and one on the other, differing in channel configuration. ADUM1402BRWZ is a legacy part with lower 2500 Vrms isolation. Verify pin compatibility and electrical performance when substituting.
