ADUM2401BRWZ-RL

Overview

The ADUM2401BRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 10 Mbps. The device features a 5000 Vrms isolation voltage and a common-mode transient immunity of 25 kV/µs. It is housed in a 16-SOIC package with a width of 7.50 mm. The component functions unidirectionally with a channel configuration of 3 inputs on side 1 and 1 input on side 2. Operating temperatures range from -40°C to +105°C.

Feature Summary

• Integrates four independent digital channels using monolithic air core transformer technology for robust signal transmission.
• Provides high common-mode transient immunity to withstand rapid voltage changes across isolation barriers.
• Delivers precise timing characteristics with low pulse width distortion and channel-to-channel matching.
• Supports standard CMOS logic levels without requiring external biasing components for basic operation.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral devices.
• Medical equipment interfaces needing reliable signal separation for patient safety compliance.
• Power electronics control circuits isolating gate drivers from low-voltage logic controllers.
• Data acquisition systems protecting sensitive analog front-ends from digital noise interference.

Procurement Notes

Verify the specific suffix 'BRWZ-RL' against official Analog Devices documentation to confirm the exact tape-and-reel packaging and temperature grade. Ensure compatibility with existing PCB footprints for the 16-SOIC package. Confirm that the 10 Mbps data rate meets system requirements. Check for any recent product change notices affecting pinout or electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when high-speed bidirectional communication is not required, as it supports only unidirectional data flow. Consider the 5000 Vrms isolation rating for applications demanding significant potential difference between circuit domains. Evaluate the 10 Mbps limit against system clock speeds to prevent data loss. The wide operating temperature range makes it suitable for harsh industrial environments where thermal stability is critical for long-term reliability.

Part Context

This part belongs to the ADuM240x family of quad-channel digital isolators. It shares the same physical footprint and basic functionality with variants like the ADUM2401ARIZ-RL but differs in speed and performance metrics. The family utilizes proprietary iCoupler technology to replace traditional optocouplers, offering superior size efficiency and consistency. It serves as a direct replacement for legacy isolation solutions in space-constrained designs.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the ADUM2401BRIZ and ADUM2401BRIZ-RL. Verify pin compatibility and electrical specifications before substitution. Other alternatives may exist but require careful validation of isolation ratings and data rates to ensure functional equivalence in the target application.
