ADUM230D1BRIZ

Overview

The ADUM230D1BRIZ is a triple-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides robust isolation with a rated insulation voltage of 5000 Vrms and a common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mb/s with a typical propagation delay of 7.2 ns. Operating on a single supply voltage between 1.7 V and 5.5 V, it draws approximately 9.4 mA per channel. It is housed in a 16-lead SOIC package and functions within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Triple-channel unidirectional signal isolation using proprietary iCoupler magnetic coupling technology
• High common-mode transient immunity of 75 kV/µs for reliable operation in noisy environments
• Integrated DC-to-DC converter capability allows isolated power delivery across the isolation barrier
• Compliant with international safety standards including UL, CSA, and VDE certifications

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced isolation barriers
• Power metering and energy management circuits
• Inverter and motor control gate drive interfaces

Procurement Notes

Verify the specific suffix 'D1' to confirm the channel configuration (3:0) and directionality. Ensure the package type matches the required PCB footprint, as variants exist in both SOIC and SOIC_W formats. Confirm RoHS compliance status for the specific manufacturing lot. Check for any recent Product Change Notifications that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when high-speed data transmission is required alongside significant voltage isolation. The 150 Mb/s rate suits most digital communication protocols like SPI and UART. Consider the ADUM230E variant if higher reliability metrics are needed for automotive applications. Evaluate power consumption requirements against the 9.4 mA per channel specification. Ensure the system ground references allow for the unidirectional signal flow supported by this specific model.

Part Context

This part belongs to the ADuM230 series of robust digital isolators from Analog Devices. It is designed to replace bulky transformer and optocoupler solutions in modern electronic designs. The series emphasizes small form factor integration while maintaining high isolation voltages. It serves as a critical interface component in systems where noise immunity and signal integrity are paramount.

Replacement Considerations

The ADUM230E1BRIZ is a qualified alternative offering enhanced performance specifications. Verify that the substitute maintains the same 16-SOIC package dimensions for direct board compatibility. Confirm that the replacement meets all necessary safety certification requirements for the end application.
