ADUM320N0BRIZ

Overview

The ADUM320N0BRIZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology. It features a 2:0 channel configuration with unidirectional signal paths. The device supports data rates up to 150 Mbps and offers high common-mode transient immunity of 100 kV/µs. Operating voltage ranges from 2.25 V to 5.5 V on both sides. It provides isolation voltages of 5700 VRMS (SOIC_IC) or 3000 VRMS (SOIC_N). Maximum propagation delay is 10 ns at 5 V, with pulse width distortion under 3 ns. It operates within a temperature range of -40°C to +125°C and is available in an 8-pin SOIC package.

Feature Summary

• Integrates CMOS technology with monolithic air-core transformer capabilities for robust magnetic coupling isolation.
• Provides independent data channels with configurable fault-safe output states for low input power conditions.
• Supports voltage translation between 2.25 V and 5.5 V systems across the isolation barrier.

Applications

• Inverter control circuits
• Power supply feedback loops
• Industrial fieldbus isolation
• PWM controller signal isolation

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and orientation. The 'N' suffix typically denotes the narrow-body SOIC variant, while 'W' indicates wide-body. Ensure the ordering code matches the required insulation voltage rating and safety certification standards for your target application region. Confirm availability status as distribution may vary.

Selection Notes

Select this component when high-speed bidirectional isolation is not required due to its unidirectional nature. It is suitable for applications demanding high CMTI and extended temperature operation. Compare channel count and isolation voltage requirements against similar parts like the ADUM321N series if bidirectional communication is needed.

Part Context

This part belongs to the ADuM320N/ADuM321N family of dual-channel digital isolators. These devices are designed for general-purpose isolation tasks requiring high reliability and speed. The family utilizes proprietary iCoupler technology to replace traditional optocouplers in many industrial and automotive applications.

Replacement Considerations

Public confirmed substitute part numbers include ADUM320N0BRIZ-RL for reel packaging variants. Cross-reference with ADUM321N series if bidirectional channels are necessary instead of the 2:0 configuration.
