ADUM231D0BRWZ-RL

Overview

The ADUM231D0BRWZ-RL is a triple-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation voltage with a minimum common-mode transient immunity of 75kV/µs. The device supports data rates up to 150Mbps and operates within a supply voltage range of 2.25V to 5.5V. It features unidirectional signal transmission across three channels in a 16-lead SOIC_W package, designed for robust performance in harsh electrical environments.

Feature Summary

• Triple-channel architecture with 2:1 channel directionality configuration
• High common-mode transient immunity of 75kV/µs for noise rejection
• Integrated input disable functionality for system control
• Robust 5000Vrms isolation barrier using magnetic coupling

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety barriers
• Power electronics interfaces such as motor drives
• Inverters and converters with noisy ground potentials

Procurement Notes

Verify the specific suffix 'D0' indicates the 2:1 channel directionality variant. Confirm the 'WZ' package denotes the wide-body SOIC format. Ensure the '-RL' suffix matches the required reel packaging quantity. Cross-reference the datasheet revision date to confirm current specifications. Validate RoHS compliance status through official manufacturer documentation.

Selection Notes

Select this component when triple-channel isolation is required with asymmetric directionality. The 75kV/µs CMTI rating suits applications with high dv/dt noise. The 150Mbps speed supports standard industrial communication protocols. Consider the 16-lead package footprint for PCB layout constraints. Verify operating temperature range requirements against the -40°C to +125°C specification.

Part Context

This part belongs to the ADuM231 family of general-purpose digital isolators. It complements other iCoupler devices by offering a specific 2:1 channel split. The technology replaces traditional optocouplers with higher reliability and lower power consumption. It is part of Analog Devices' broader portfolio of isolated interface solutions.

Replacement Considerations

Direct substitutes include ADUM231E variants for extended temperature ranges. Check ADUM230 series for single-channel alternatives. Verify pin compatibility with ADUM231D0BRIZ-RL if tape-and-reel quantities differ. Ensure isolation voltage ratings match or exceed original design requirements.
