ADUM3300BRWZ

Overview

The ADUM3300BRWZ is a three-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It provides 2500Vrms isolation voltage with a data rate of 10Mbps and common mode transient immunity of 25kV/µs. The device operates on a single supply voltage range of 2.7V to 5.5V, featuring unidirectional channel configuration. It is housed in a 16-SOIC package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS logic with single-chip air-core transformer technology for robust signal transmission.
• Provides galvanic isolation between circuit sections without requiring external optical components.
• Offers superior performance characteristics compared to traditional optocoupler alternatives.

Applications

• General purpose digital isolation in industrial control systems
• Isolating communication interfaces in noisy environments
• Protecting sensitive electronics in power monitoring applications

Procurement Notes

Verify the specific suffix BRWZ to confirm the tape-and-reel packaging variant and RoHS compliance status. Confirm that the component meets AEC-Q100 requirements if automotive qualification is necessary, as standard industrial versions may differ. Ensure the ordering part number matches the exact channel count and directionality specified in the design schematic.

Selection Notes

Select this component when three independent unidirectional channels are required within a single package. It is suitable for designs needing moderate data rates up to 10Mbps with high noise immunity. Consider the 16-SOIC footprint for PCB layout constraints. Evaluate power consumption against other iCoupler variants if low standby current is critical.

Part Context

This device belongs to the ADuM330x series of digital isolators. These parts combine analog and digital functions on a single monolithic CMOS substrate. The series is designed to replace optocouplers in applications requiring higher reliability and lower power consumption while maintaining electrical safety standards.

Replacement Considerations

Direct substitutes include other ADuM330x family members such as ADUM3301ARWZ or ADUM3301WARWZ, which offer similar isolation but may vary in channel directionality or speed. Verify pin compatibility and functional equivalence before swapping.
