ADUM340E0WBRQZ-RL7

Overview

The ADUM340E0WBRQZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional data channels with a maximum data rate of 150 Mb/s at 5V operation. The device provides an insulation voltage of 5700 Vrms and supports supply voltages ranging from 2.25V to 5.5V on both sides. Key electrical parameters include a typical propagation delay of 6.2 ns (maximum 10 ns), pulse width distortion of less than 3 ns, and a typical common-mode transient immunity of 180 kV/µs. It operates within a temperature range of -40°C to +125°C and is housed in a 16-lead SOIC package.

Feature Summary

• Integrates high-speed CMOS with monolithic air-core transformer technology for robust magnetic isolation
• Provides independent data channels with flexible configuration options for multi-directional signal transfer
• Ensures strict channel matching with minimal pulse width distortion for precise timing applications
• Offers enhanced electrostatic discharge protection on input/output pins and across the isolation barrier

Applications

• Isolation for Serial Peripheral Interface (SPI) communication links
• Data converter isolation in industrial measurement systems
• Isolation for RS-485 and Controller Area Network (CAN FD) interfaces
• PWM controller signal isolation in power electronics
• General-purpose multi-channel digital signal isolation

Procurement Notes

Verify the specific suffix '0' indicates the output state configuration (typically fault-safe low or similar variant depending on the exact datasheet revision). Confirm the 'W' suffix denotes the wide-body 16-SOIC package dimensions. Check current availability status as automotive-grade components may have restricted supply chains. Ensure the ordering part number matches the required insulation voltage and channel directionality specifications for the target design.

Selection Notes

Select this component when high-speed data rates up to 150 Mb/s are required alongside high isolation voltage ratings. The wide operating voltage range allows compatibility with lower voltage logic systems on either side of the isolation barrier. Consider the thermal performance and package size if space constraints exist. Verify that the common-mode transient immunity meets the noise environment requirements of the application.

Part Context

This part belongs to the ADuM34xE family of quad digital isolators designed for demanding industrial and automotive applications. The E-series variants typically offer enhanced performance characteristics compared to standard versions. The ADUM340E0 variant specifically configures all four channels in a single direction, suitable for parallel data bus isolation or multi-line control signals requiring galvanic separation.

Replacement Considerations

Direct replacements within the same family include ADUM340E1WBRQZ-RL7 and ADUM340E2WBRQZ-RL7, which differ primarily in channel directionality configurations. Cross-family alternatives from other manufacturers would require careful evaluation of pinout compatibility, isolation voltage ratings, and data speed specifications.
