ADUM141E0BRQZ-RL7

Digital Isolators Overview

The ADUM141E0BRQZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four channels with three unidirectional forward paths and one reverse channel. The device operates within a supply voltage range of 1.7 V to 5.5 V and supports data rates up to 150 Mb/s. Key electrical specifications include an isolation voltage of 3000 Vrms, a common mode transient immunity of 75 kV/µs, and a propagation delay of 15 ns. It functions reliably across an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four isolated channels using on-chip transformer-based magnetic coupling for high-speed signal transmission.
• Provides robust protection against common mode transients with specified immunity ratings.
• Includes an output enable function for controlled signal gating and power management.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripherals
• Medical equipment interfaces needing certified insulation barriers
• Power electronics control circuits for inverter gate driving

Digital Isolators Procurement Notes

Verify the specific suffix 'QZ' confirms the QSOP-16 package and reel packaging format. Confirm RoHS compliance status through official manufacturer documentation. Ensure the part number matches the required 3000 Vrms isolation rating rather than the 3750 Vrms variant found in other series members. Check humidity sensitivity classification for storage and handling requirements.

Digital Isolators Selection Notes

Select this component when a quad-channel isolator with mixed directionality (3:1) is required. The QSOP-16 package offers a compact footprint suitable for space-constrained designs. Consider the 150 Mb/s data rate limit for high-speed communication needs. Evaluate the 11.4 mA supply current against total system power budgets compared to lower-power alternatives.

Digital Isolators Part Context

This part belongs to the ADuM141ES series of robust digital isolators. It differs from the ADUM141E0BRWZ variant primarily by its QSOP-16 package instead of SOIC-16 and its specific 3000 Vrms isolation rating. The 'RL7' suffix indicates tape and reel packaging for automated assembly processes.

Digital Isolators Replacement Considerations

The ADUM141E0BRWZ serves as a pin-compatible alternative but utilizes an SOIC-16 package and offers 3750 Vrms isolation. Verify package dimensions and thermal characteristics before substitution. Other ADuM141x family members may require schematic adjustments due to differing channel configurations or isolation ratings.
