ADUM3401CRWZ-RL

Overview

The ADUM3401CRWZ-RL is a quad-channel digital isolator utilizing Analog Devices iCoupler technology. It features four independent channels with a data rate of 90 Mb/s and an isolation voltage of 2500 Vrms. The device operates on a supply voltage range of 2.7 V to 5.5 V, with typical power consumption of 32 mA on the source side and 59 mA on the drain side. Propagation delay is typically 32 ns, with rise and fall times of approximately 3 ns. It supports bidirectional signal transmission and functions within an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent digital isolation channels using monolithic air core transformer technology for high-speed signal transmission.
• Provides robust electrical isolation with a rated insulation voltage of 2500 Vrms to protect sensitive circuitry.
• Supports bidirectional data flow across all channels, allowing flexible configuration for various interface protocols.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral devices.
• Medical equipment interfaces needing certified isolation for patient safety and noise immunity.
• Power electronics control circuits where high common-mode transient immunity is critical.

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing components. Confirm that the CRWZ designation corresponds to the commercial temperature grade and SOIC-16 package variant. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when bidirectional communication is required across four isolated channels. It is suitable for applications demanding moderate data rates up to 90 Mb/s without the need for external isolation transformers. Consider the power consumption profile relative to system battery life or thermal constraints in dense PCB designs.

Part Context

This part belongs to the ADUM340x series of quad-channel digital isolators from Analog Devices. It shares the same functional architecture as the ADUM3401CRWZ but differs in packaging format. The series leverages silicon dioxide isolation technology to replace traditional magnetic couplers in compact form factors.

Replacement Considerations

The ADUM3401CRWZ serves as the tube-packaged equivalent. Verify pinout compatibility if substituting with other quad-channel isolators from different manufacturers.
