ADUM341E1WBRQZ-RL7

Overview

The ADUM341E1WBRQZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features a 16-pin QSOP package and supports unidirectional data flow at speeds up to 150 Mb/s. The device operates on supply voltages between 2.25 V and 5.5 V. It provides an insulation voltage of 3 kVrms and a reinforced isolation rating of 5.7 kVrms. The component is qualified under AEC-Q100 standards for automotive applications and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Employs proprietary iCoupler magnetic coupling technology to provide robust electrical isolation without the need for external transformer drivers.
• Offers high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Integrates four independent channels with a 3:1 input-to-output configuration for efficient bidirectional system interfacing.
• Meets automotive reliability requirements through AEC-Q100 qualification for sustained operation in demanding conditions.

Applications

• CAN bus interface isolation in automotive electronic control units
• RS-485 communication link isolation in industrial automation systems
• SPI interface isolation for sensor networks and data acquisition modules

Procurement Notes

Verify the specific suffix QZ against official documentation to confirm package type and tape-and-reel configuration. Confirm AEC-Q100 automotive qualification status directly with the manufacturer or authorized distributors. Ensure compatibility with existing PCB footprints for the QSOP-16 package before finalizing procurement decisions.

Selection Notes

Select this component when high-speed data rates up to 150 Mb/s are required alongside significant isolation barriers. Consider the 3:1 channel configuration for applications needing more inputs than outputs. Evaluate the thermal performance within the specified operating temperature range to ensure reliable long-term operation in enclosed spaces.

Part Context

This part belongs to the ADuM341 family of quad-channel digital isolators designed for high-performance isolation needs. It complements other variants like the ADUM341E0 series by offering specific insulation ratings and automotive certifications suitable for critical infrastructure and vehicle electronics.

Replacement Considerations

The ADUM341E0WBRWZ is listed as a parameter-equivalent alternative. Verify that the insulation voltage and channel configuration match the original design requirements before substitution.
