ADUM341E0WBRQZ-RL7

Overview

The ADUM341E0WBRQZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 3:1 channel configuration with three forward and one reverse channel. The device supports data rates up to 150 Mb/s and operates on supply voltages between 2.25 V and 5.5 V. It provides insulation voltages of 3 kVrms and 5.7 kVrms, with a typical propagation delay of 6.2 ns. Packaged in a 16-pin QSOP, it is AEC-Q100 qualified for automotive applications.

Feature Summary

• Integrates four independent digital isolation channels using monolithic air-core transformer technology for high-speed signal transmission.
• Provides enhanced safety ratings including UL certification at 5700 VRMS and compliance with international standards such as IEC 62368-1.
• Features fault-safe output options ensuring defined logic states during power loss or signal interruption.

Applications

• Isolation for Serial Peripheral Interface (SPI) communication links
• Signal isolation in RS-485 and Controller Area Network (CAN) systems
• Isolation for industrial fieldbus networks and PWM controller signals

Procurement Notes

Verify the specific suffix 'QZ' indicates automotive qualification under AEC-Q100 standards. Confirm the 'E0' designation corresponds to the fault-safe low output logic level required by the circuit design. Ensure the QSOP-16 package dimensions match the PCB footprint constraints. Check current availability status as distribution may be limited.

Selection Notes

Select this component when a 3:1 unidirectional channel ratio is required within a quad-channel isolator. The E0 variant is appropriate for applications necessitating a default low output state. Consider the 5.7 kVrms isolation barrier for high-voltage noise environments. Evaluate the 150 Mbps speed against system timing requirements.

Part Context

This part belongs to the ADuM34xE family of quad digital isolators. It shares the same core iCoupler architecture and 16-pin QSOP packaging as variants like the ADUM341E1WBRQZ-RL7, differing primarily in channel directionality and output logic levels. The family is designed for robust isolation in noisy industrial and automotive settings.

Replacement Considerations

The ADUM341E1WBRQZ-RL7 serves as a parameter-equivalent alternative within the same series. Verify that the E1 variant's fault-safe high output logic aligns with the application requirements before substitution.

FAQ

What does the 'E0' suffix indicate regarding output behavior?

The 'E0' suffix denotes a fault-safe low output configuration, meaning the outputs default to a low logic state if the device loses power or experiences a fault condition.

Is this component suitable for automotive applications?

Yes, the ADUM341E0WBRQZ-RL7 is AEC-Q100 qualified, making it suitable for use in automotive electronic systems.
