ADUM3300CRWZ

Overview

The ADUM3300CRWZ is a triple-channel digital isolator from Analog Devices, utilizing iCoupler technology to integrate high-speed CMOS circuitry with single-chip air-core transformer isolation. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device provides an insulation voltage of 2500 Vrms and exhibits a common-mode transient immunity of 25 kV/µs. Key timing parameters include a propagation delay of 27 ns and rise/fall times of 3 ns typical. It functions in unidirectional mode across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS technology with single-chip air-core transformer isolation for robust signal transmission.
• Provides enhanced system-level ESD reliability compared to traditional optocoupler alternatives.
• Features magnetic coupling isolation with high common-mode transient immunity.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications with high-voltage interfaces

Procurement Notes

Verify the specific suffix 'CRWZ' against the manufacturer's current datasheet to confirm package type (SOIC-16) and temperature grade. Ensure compatibility with existing PCB footprints and voltage levels. Confirm availability status as distribution channels may indicate limited stock or discontinuation risks. Cross-reference pinouts with legacy components if replacing older isolation devices.

Selection Notes

Select this component when three isolated channels are required with high data throughput up to 90 Mb/s. It is suitable for designs demanding superior ESD performance and lower power consumption than optical isolators. Consider the SOIC-16 package constraints and ensure the application environment stays within the specified -40°C to +105°C operational range.

Part Context

This part belongs to the ADuM330x series of triple-channel digital isolators. It represents Analog Devices' implementation of iCoupler technology, which replaces bulky magnetic components with on-chip transformers. This series is designed to offer better performance characteristics, including higher speed and lower power, compared to conventional optocouplers in industrial and commercial interface applications.

Replacement Considerations

Direct replacements should be sought within the ADuM330x family or comparable triple-channel isolators from other manufacturers. Verify that substitute parts match the 16-pin SOIC footprint and support the required 90 Mb/s data rate. Check for equivalent insulation voltage ratings and CMTI specifications to maintain system safety integrity.
