ADUM141D0BRZ

Digital Isolators Overview

The ADUM141D0BRZ is a robust quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 3:1 channel configuration with four channels in a 16-lead SOIC package. Key electrical parameters include a data rate of 150 Mb/s, an insulation voltage of 3000 Vrms, and a common-mode transient immunity of 75 kV/µs. The device operates on a supply voltage range of 1.8 V to 5 V, with a maximum propagation delay of 15 ns and typical rise/fall times of 2.5 ns.

Digital Isolators Feature Summary

• Integrates four independent isolation channels using proprietary iCoupler magnetic coupling technology for signal transmission across isolation barriers.
• Provides high common-mode transient immunity to prevent false triggering in noisy industrial environments.
• Supports unidirectional data flow with configurable channel layouts to simplify circuit design.
• Operates within a wide temperature range suitable for demanding industrial applications.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors.
• Medical equipment needing reliable signal isolation for patient safety compliance.
• Power electronics interfaces for monitoring and control circuits in motor drives.
• Communication gateways isolating different voltage domains in data acquisition systems.

Digital Isolators Procurement Notes

Verify the specific suffix (e.g., BRZ) against the official datasheet to confirm package type and insulation rating. Confirm availability status as distribution listings may indicate limited stock or discontinuation. Ensure the selected variant matches the required operating voltage and thermal specifications for the target application environment before finalizing procurement.

Digital Isolators Selection Notes

Select this component when a quad-channel isolator with 3000 Vrms insulation is required. Compare against the ADUM141D0BRWZ if higher 3750 Vrms insulation is needed. Consider the ADUM141D0BRQZ for QSOP packaging requirements. Verify that the 150 Mb/s data rate meets system timing constraints and that the 1.8 V to 5 V supply range aligns with the host logic levels.

Digital Isolators Part Context

This part belongs to the ADuM141D series of robust digital isolators. It is designed for general-purpose isolation tasks where high reliability and low power consumption are critical. The series leverages silicon dioxide (SiO2) isolation technology to provide superior performance compared to traditional optocouplers in terms of speed and consistency.

Digital Isolators Replacement Considerations

Direct replacements include ADUM141D0BRWZ for higher insulation voltage or ADUM141D0BRQZ for alternative packaging. Cross-referencing pinouts and electrical characteristics with the original datasheet is essential to ensure compatibility without redesigning the PCB layout.
