ADUM241E1BRWZ

Overview

The ADUM241E1BRWZ is a robust quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides electrical isolation with a rated insulation voltage of 5000 Vrms and supports data rates up to 150 Mb/s. The device features a 3:1 channel configuration (three forward, one reverse) and operates on a supply voltage range of 1.7V to 5.5V. Key performance metrics include a maximum propagation delay of 13 ns, a minimum common-mode transient immunity (CMTI) of 75 kV/µs, and an operating temperature range from -40°C to +125°C. It is housed in a 16-lead SOIC package.

Feature Summary

• Utilizes monolithic air core transformer technology for high-speed signal transmission without optical components.
• Provides robust galvanic isolation with high common-mode transient immunity for noisy environments.
• Supports bidirectional communication through a flexible 3:1 channel architecture.
• Operates across a wide industrial temperature range with low power consumption.

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits for motor drives
• Automotive infotainment and body control modules

Procurement Notes

Verify the specific suffix 'BRWZ' to confirm the tube packaging format and lead-free status. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check for AEC-Q100 qualification if automotive reliability standards are required. Confirm supply availability as distribution may vary by region.

Selection Notes

Select this component when high isolation voltage and moderate data speeds are required. Compare CMTI ratings against noise environment requirements. Consider the 1.7V to 5.5V supply range for compatibility with various logic levels. Evaluate thermal performance within the specified -40°C to +125°C range for the target application.
