ADUM141E1WBRQZ

Digital Isolators Overview

The ADUM141E1WBRQZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It features four independent channels with three unidirectional forward paths and one reverse path, supporting data rates up to 150 Mb/s. The device provides an insulation voltage of 3750 Vrms and withstands a common-mode transient immunity of 75 kV/µs. Operating on supply voltages between 1.7 V and 5.5 V, it draws 11.4 mA typical current. Propagation delay is 15 ns with rise/fall times of 2.5 ns. It is AEC-Q100 qualified for automotive use and operates from -40°C to +125°C in a QSOP-16 package.

Digital Isolators Feature Summary

• Integrates iCoupler magnetic coupling technology for high-speed signal isolation without optical components
• Provides robust 3750 Vrms insulation with 75 kV/µs common-mode transient immunity
• Features patented refresh technology ensuring DC correctness during power transitions
• Supports bidirectional communication with configurable default output states

Digital Isolators Applications

• Automotive motor control systems requiring isolated gate drive signals
• Industrial fieldbus isolation for sensor interfaces
• Isolation of ADC/DAC data lines in measurement equipment
• Inverter and converter control circuitry

Digital Isolators Procurement Notes

Verify the specific suffix 'QZ' indicates automotive qualification (AEC-Q100) and the 'RL7' denotes reel packaging. Confirm the manufacturer part number matches Analog Devices documentation exactly. Check for moisture sensitivity level requirements during storage and handling. Ensure the supplier provides valid traceability records for automotive-grade components.

Digital Isolators Selection Notes

Select this component when high-speed isolation exceeding 100 Mbps is required alongside automotive reliability standards. The 3:1 channel configuration suits applications needing more forward outputs than reverse inputs. Compare against standard industrial grades if automotive certification is unnecessary. Verify that the 15 ns propagation delay meets system timing constraints.

Digital Isolators Part Context

This part belongs to the ADUM141ES series of quad-channel digital isolators. It shares the core iCoupler architecture with variants like the ADUM141E0BRZ but differs in insulation rating and qualification. The E1 variant specifically offers higher insulation voltage compared to lower-rated models within the same family.
