ADUM141E1BRZ

Digital Isolators Overview

The ADUM141E1BRZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 3000 Vrms isolation voltage with a data rate of 150 Mb/s and common-mode transient immunity of 75 kV/µs. The device operates on a supply voltage range of 1.7 V to 5.5 V, drawing 11.4 mA typical current. Propagation delay is 15 ns maximum, with rise and fall times of 2.5 ns. It features unidirectional channels in a 16-SOIC package and supports an operating temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four independent digital isolation channels within a single compact package.
• Employs iCoupler technology for high-speed signal transmission without optical components.
• Provides robust common-mode transient immunity to protect against electrical noise.
• Supports wide supply voltage ranges for flexible system integration.

Digital Isolators Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and energy monitoring
• Automotive electronic control units

Digital Isolators Procurement Notes

Verify the specific suffix BRZ indicates the lead-free RoHS-compliant variant in the 16-SOIC package. Confirm the E1 designation corresponds to the 3000 Vrms insulation rating rather than higher voltage variants. Ensure compatibility with standard surface-mount assembly processes for SOIC-16 components.

Digital Isolators Selection Notes

Select this component when bidirectional isolation is not required due to its unidirectional channel configuration. Consider the 150 Mb/s data rate limit for high-speed communication needs. Evaluate the 3000 Vrms isolation barrier against system safety requirements compared to higher-rated E0 or E2 series options.

Digital Isolators Part Context

This part belongs to the ADuM141ES family of robust digital isolators from Analog Devices. It shares the same pinout and functional architecture as other variants in the series, differing primarily in insulation voltage ratings and qualification standards. The family utilizes proprietary silicon-on-insulator technology for reliable performance.

Digital Isolators Replacement Considerations

The ADUM141E0BRZ serves as a direct substitute offering higher 3750 Vrms isolation while maintaining identical pinouts and functionality. Verify that the increased voltage rating meets system requirements without causing unnecessary cost implications.
