ADUM230D1BRWZ

Overview

The ADUM230D1BRWZ is a triple-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides robust signal isolation with a rated insulation voltage of 5000 Vrms and a minimum common-mode transient immunity (CMTI) of 75 kV/µs. The device supports data rates up to 150 Mbps with a typical propagation delay of 7.2 ns. It operates on a single supply voltage ranging from 1.7 V to 5.5 V and features unidirectional channel configuration (3 inputs, 0 outputs). The component is housed in a 16-lead SOIC Wide package and is qualified for operation across an extended temperature range of -40°C to +125°C.

Feature Summary

• Utilizes monolithic air core transformer technology for high-speed digital isolation without external magnetics
• Provides robust noise immunity with 75 kV/µs common-mode transient rejection capability
• Integrates three independent unidirectional channels within a compact surface-mount package

Applications

• Industrial communication bus isolation such as RS-485 and CAN
• Isolated gate drive circuits for power electronics
• Medical equipment requiring reinforced isolation barriers
• Data acquisition systems with high-voltage ground separation

Procurement Notes

Verify the specific suffix 'BRWZ' against official Analog Devices documentation to confirm the tape-and-reel packaging format and RoHS compliance status. Ensure the procurement source provides valid traceability for the iCoupler series. Cross-reference the part number with the latest datasheet revision history to account for any recent manufacturing site changes or specification updates documented in Product Change Notifications.

Selection Notes

Select this component when designing systems requiring triple-channel isolation with high CMTI performance. The 150 Mbps data rate suits most industrial serial communication standards. Consider the 16-lead SOIC package dimensions for PCB layout constraints. Verify that the required isolation voltage meets the 5000 Vrms rating for the specific safety standards applicable to the end application.

Part Context

This part belongs to the ADuM230 family of iCoupler digital isolators. These devices integrate high-speed CMOS logic and monolithic coil technology on a single silicon chip. The family offers various channel configurations and insulation ratings, providing a compact alternative to traditional optocouplers while maintaining low power consumption and high reliability in harsh electromagnetic environments.

Replacement Considerations

Direct replacements include other members of the ADUM230 series such as ADUM230D1BRIZ or ADUM230E1BRIZ, depending on the required packaging type (tube vs. reel) and specific qualification grades. Verify pinout compatibility and electrical parameters before substitution.
