ADUM230D0BRIZ-RL

Overview

The ADUM230D0BRIZ-RL is a triple-channel digital isolator manufactured by Analog Devices Inc. It utilizes magnetic coupling technology to provide robust signal isolation with an insulation voltage of 5000 Vrms. The device operates within a supply voltage range of 1.7 V to 5.5 V and supports data rates up to 150 Mb/s. Key electrical parameters include a propagation delay of 7.2 ns, a typical operating supply current of 9.4 mA, and rise/fall times consistent with the specified data rate. It is housed in a SOIC-16 package and functions as a unidirectional isolator suitable for harsh industrial environments.

Feature Summary

• Provides galvanic isolation across three independent channels using magnetic coupling technology
• Supports high-speed data transmission with a maximum data rate of 150 Mb/s
• Features low propagation delay for precise timing in synchronous communication systems

Applications

• Industrial automation control systems requiring isolated sensor interfaces
• Medical equipment needing reliable patient-side isolation barriers
• Power electronics gate drive circuits for inverters and motor drives

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix indicates reel packaging if required for automated assembly. Check for recent Product Change Notifications (PCN) regarding manufacturing site updates or material changes. Ensure storage conditions comply with moisture sensitivity levels prior to soldering. Validate that the received part matches the ordering number exactly to avoid functional mismatches.

Selection Notes

Select this component when three isolated bidirectional or unidirectional channels are required within a single package. Consider the 5000 Vrms insulation rating for safety-critical applications. Evaluate the 150 Mb/s data rate against system bandwidth requirements. Compare power consumption at 9.4 mA against battery-operated constraints. Ensure the SOIC-16 footprint fits the available PCB space compared to wider packages.

Part Context

This part belongs to the ADuM230 series of robust digital isolators from Analog Devices. These devices are designed for high reliability in noisy environments where traditional optocouplers may fail. The series emphasizes long-term stability and consistent performance over temperature variations, making it suitable for automotive and industrial sectors demanding high durability.

Replacement Considerations

Direct pin-to-pin replacements should be verified against official cross-reference lists. Alternative parts must match the 5000 Vrms isolation rating and SOIC-16 package dimensions. Verify that substitute components support the same 150 Mb/s data rate and 7.2 ns propagation delay characteristics to maintain system timing integrity.
