ADUM341E1WBRWZ

Overview

The ADUM341E1WBRWZ is a four-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features a 5700Vrms isolation rating and supports data rates up to 150Mbps. The device operates on supply voltages ranging from 2.25V to 5.5V. Key electrical parameters include a maximum propagation delay of 10ns, pulse width distortion under 3ns, and a minimum common-mode transient immunity of 100kV/µs. It provides a 3:1 channel configuration (three inputs to one output) with unidirectional signal paths. The component is housed in a 16-lead SOIC package and is qualified for automotive applications under AEC-Q100 standards.

Feature Summary

• Integrates high-speed CMOS with monolithic air-core transformer technology for robust signal transmission across the isolation barrier.
• Provides independent data channels allowing flexible configuration for various interface protocols such as SPI, CAN, and RS-485.
• Features fault-safe design ensuring outputs transition to a predetermined high state when input power is removed.
• Delivers high common-mode transient immunity to maintain signal integrity in electrically noisy industrial environments.

Applications

• Isolation for Controller Area Network (CAN) and CAN FD interfaces
• Signal isolation for Serial Peripheral Interface (SPI) communication
• Data conversion isolation in industrial measurement systems
• PWM controller signal isolation in motor drive applications

Procurement Notes

Verify the specific suffix 'WBRWZ' against the manufacturer's current datasheet to confirm pinout compatibility and packaging details. Ensure the selected variant matches the required fault-safe logic level and voltage domain specifications for the target application circuit design.

Selection Notes

Select this component when high-speed data transfer exceeding 100Mbps is required alongside stringent isolation voltage requirements. The 3:1 channel architecture is optimal for applications needing multiple input signals routed to a single output line within an isolated boundary.

Part Context

This part belongs to the ADuM34xE series of quad-channel digital isolators. The 'E1' designation indicates the fault-safe output state is high upon loss of input power. The 'W' suffix denotes the wide-body 16-SOIC package designed to meet creepage and clearance distance requirements for reinforced insulation ratings.

Replacement Considerations

ADUM341E0WBRWZ offers identical specifications but with a fault-safe low output state instead of high.

FAQ

What is the typical common-mode transient immunity value?

The device guarantees a minimum common-mode transient immunity of 100kV/µs.

Does the device support bidirectional data transmission?

No, the ADUM341E1WBRWZ supports only unidirectional data flow from the input side to the output side.
