ADUM320N0BRZ-RL7

Overview

The ADUM320N0BRZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 150 Mb/s data rate and 3000 Vrms insulation voltage in an 8-pin SOIC package. The device operates on supply voltages between 2.25 V and 5.5 V with a typical quiescent current of 3.1 mA per channel. Propagation delay is 10 ns maximum, supporting temperatures from -40°C to +125°C.

Feature Summary

• Integrates CMOS circuitry with monolithic air-core transformer technology for robust signal isolation.
• Provides high common-mode transient immunity to suppress radiated and conducted noise effectively.
• Supports bidirectional voltage translation across the isolation barrier within specified input ranges.

Applications

• Inverter control systems
• Industrial fieldbus isolation
• PWM controller signal isolation

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the N0 designation corresponds to the fault-safe low output state required by the design. Ensure compatibility with the 8-SOIC footprint and check moisture sensitivity levels prior to assembly processing.

Selection Notes

Select this component for applications requiring high-speed data transmission up to 150 Mbps with moderate isolation requirements. It is suitable where low power consumption and wide operating temperature ranges are critical. Consider alternative packages if higher isolation ratings or different pin counts are needed.

Part Context

This part belongs to the ADUM320N series of dual-channel digital isolators. It shares architectural similarities with other iCoupler devices but is distinguished by its specific insulation rating and channel configuration. The series supports various automotive and industrial certifications.

Replacement Considerations

ADUM320N0WBRIZ-RL7 offers equivalent electrical performance with a wider body package option.
