ADUM140D1BRWZ-RL

Overview

The ADUM140D1BRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mbps and a common-mode transient immunity (CMTI) of 75 kV/µs. The device operates on a supply voltage range of 1.7 V to 5.5 V and provides an isolation voltage of 3750 Vrms. Packaged in a 16-pin WSOIC, it supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Utilizes proprietary iCoupler magnetic coupling technology for robust signal isolation without external transformers.
• Provides high common-mode transient immunity to maintain signal integrity in noisy environments.
• Supports unidirectional data transmission across four independent channels.
• Operates within a wide supply voltage range suitable for various logic levels.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power electronics control circuits
• Automotive electronic modules

Procurement Notes

Verify the specific suffix 'W' indicates the wider SOIC package width compared to standard variants. Confirm the '-RL' designation corresponds to the reel packaging format required for automated assembly processes. Ensure compatibility with the target PCB footprint dimensions for the 16-Wide SOIC package before finalizing procurement orders.

Selection Notes

Select this component when unidirectional isolation is sufficient for the application design. The 150 Mbps data rate supports high-speed communication protocols. Consider the 3750 Vrms isolation rating for safety compliance requirements. The wide operating temperature range makes it suitable for harsh industrial or automotive environments where thermal stability is critical.

Part Context

This part belongs to the ADuM140 series of quad-channel digital isolators. It shares the core iCoupler architecture with other members like the ADUM1400 and ADUM1402, differing primarily in channel directionality and specific electrical characteristics. The series represents Analog Devices' solution for replacing traditional optocouplers in modern circuit designs.

Replacement Considerations

The ADUM140D1BRZ is a tube-packaged equivalent with identical electrical specifications but different packaging. Verify if the reel format is strictly necessary for production lines. Other family members like ADUM1400 offer bidirectional options which may require schematic redesigns if substituted directly.
