ADUM3301WARWZ

Overview

The ADUM3301WARWZ is a three-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. 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 an isolation voltage of 2500 Vrms with unidirectional channel polarity. Key electrical parameters include a propagation delay of 32 ns and power consumption of 28 mA or 41 mA depending on the side. It is housed in a 16-lead SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Employs magnetic coupling technology to provide robust galvanic isolation between circuits.
• Features three independent channels configured for unidirectional signal transmission.
• Includes integrated on-chip dual power supplies to simplify system design.

Applications

• Automotive electronic control units requiring high-speed isolated communication
• Industrial automation systems with noisy electrical environments
• Medical equipment needing certified safety isolation

Procurement Notes

Verify the specific suffix WARWZ against official datasheets to confirm the SOIC-16 wide-body package and tube packaging format. Confirm AEC-Q100 qualification status if automotive compliance is required. Check current availability as distribution may be limited. Ensure compatibility with existing PCB footprints for 16-lead SOIC components before ordering.

Selection Notes

Select this component when three unidirectional channels are required at speeds up to 90 Mb/s. Compare power consumption figures against other isolators if battery life is critical. Verify that the 2500 Vrms isolation rating meets the safety requirements of the application. Consider the operating temperature range of -40 C to +105 C for environmental suitability.

Part Context

This part belongs to the ADUM3301 series of digital isolators. It shares the same core architecture and specifications as variants like ADUM3301BRWZ but differs in packaging and orientation. The series is designed for general-purpose isolation in interface circuits where high reliability and speed are necessary.

Replacement Considerations

ADUM3301BRWZ is a direct functional equivalent with identical electrical specifications. Verify package orientation differences between W (wide) and B (standard) suffixes to ensure mechanical fit. Other series members like ADUM3300 offer bidirectional options but may have different pinouts or performance characteristics.
