ADUM3301WBRWZ

Overview

The ADUM3301WBRWZ is a three-channel digital isolator utilizing Analog Devices iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 90 Mb/s. The device provides 2500 Vrms isolation voltage and exhibits a propagation delay of 32 ns. It features unidirectional signal transmission with a 2/1 channel configuration (two inputs, one output). The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates three independent digital channels using proprietary magnetic coupling technology for galvanic isolation.
• Provides high common-mode transient immunity to protect against noise in electrically noisy environments.
• Includes integrated on-chip dual power supplies to simplify design and reduce external component count.
• Meets automotive qualification requirements for reliability in demanding operational conditions.

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems with high-voltage isolation needs
• Medical equipment requiring certified electrical isolation
• Power conversion circuits needing gate drive isolation

Procurement Notes

Verify the specific suffix WBRWZ to confirm the reel packaging format and ensure compatibility with automated assembly processes. Confirm that the AEC-Q100 qualification status meets your project's automotive reliability standards. Check current availability as supply may be restricted. Ensure the SOIC-16 package dimensions align with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when three isolated bidirectional or unidirectional channels are required at high speeds. The ADUM3301 offers a balance of speed and power consumption suitable for complex interface designs. Consider the 2/1 input/output configuration to determine if it matches your signal routing topology. Evaluate the thermal performance within the specified temperature range for your enclosure design.

Part Context

This part belongs to the ADUM3301 series of iCoupler digital isolators from Analog Devices. It shares architectural similarities with other members like the ADUM3300 but differs in channel directionality. The series represents a shift from traditional transformer-based isolation to integrated magnetic coupling on silicon.

Replacement Considerations

The ADUM3301WARWZ is a tube-packaged equivalent of the same functional device. Verify if the change in packaging from reel to tube impacts your manufacturing workflow. No other direct functional substitutes are confirmed in the provided documentation.
