ADUM240D1BRWZ

Overview

The ADUM240D1BRWZ is a robust quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mb/s and an isolation voltage of 5000 Vrms. The device operates on a supply voltage range of 1.7 V to 5.5 V, drawing 11.8 mA of operating current. Key electrical parameters include a propagation delay of 7.2 ns, a common-mode transient immunity (CMTI) of 75 kV/µs, and a pulse width distortion of 500 ps. It functions within a temperature range of -40°C to +125°C and is housed in a 16-SOIC package.

Feature Summary

• Provides galvanic isolation for noisy environments using proprietary iCoupler magnetic coupling technology
• Offers high common-mode transient immunity to ensure signal integrity in harsh conditions
• Features four independent unidirectional channels for versatile system integration

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing safe patient isolation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix BRWZ indicates the reel packaging format when sourcing. Confirm the D1 variant designation matches the required channel configuration. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check for RoHS compliance status if required by regional regulations. Validate that the 125°C maximum operating temperature meets the application's thermal requirements.

Selection Notes

Select this component for applications demanding high-speed data transmission up to 150 Mb/s across isolated barriers. The wide supply voltage range supports both 3.3 V and 5 V logic interfaces. Consider the 75 kV/µs CMTI rating for environments with rapid voltage transients. The unidirectional nature requires separate components for bidirectional communication needs.

Part Context

This part belongs to the ADuM240D series of robust quad-channel digital isolators. It shares the core iCoupler architecture with other variants in the family but differs in packaging and specific performance ratings. The series is designed to replace traditional optocouplers in modern industrial and medical designs.

Replacement Considerations

The ADUM240D1BRIZ is a pin-compatible alternative available in tube packaging instead of reel format. Both parts share identical electrical specifications and functionality.
