ADUM1223BRWZ-RL

Overview

The ADUM1223BRWZ-RL is a dual-channel digital isolator manufactured by Analog Devices Inc. It utilizes iCoupler technology to provide galvanic isolation between circuits. The device operates within a supply voltage range of 2.7 V to 5.5 V on both the source and destination sides. It features a common-mode transient immunity of 50 kV/µs, ensuring reliable signal transmission in high-noise environments. The component is housed in an 8-pin SOIC package and supports data rates up to 100 Mbps per channel.

Feature Summary

• Provides bidirectional signal isolation via integrated capacitive coupling technology
• Ensures high reliability with specified common-mode transient immunity ratings
• Supports flexible power supply configurations for independent side operation

Applications

• Industrial automation control systems requiring isolated communication interfaces
• Power electronics monitoring and protection circuits
• Medical equipment needing patient isolation barriers

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides traceable origin certificates to guarantee component authenticity and quality standards are met for critical applications.

Selection Notes

Select this component when dual-channel isolation is required within a compact footprint. Consider the 50 kV/µs CMTI rating for noisy industrial environments. Evaluate the 100 Mbps data rate capability against system timing requirements. Verify that the 8-pin SOIC package fits the available PCB space constraints.

Part Context

This part belongs to the ADUM1223 series of digital isolators from Analog Devices. It is designed as a cost-effective solution for replacing traditional transformer-based isolation methods. The series offers improved performance in terms of size and power consumption compared to legacy discrete isolation components.

Replacement Considerations

Direct replacements include other ADUM122x variants with compatible pinouts. Cross-reference datasheets to ensure equivalent CMTI and propagation delay specifications match the original design requirements before substitution.
