ADUM226N1BRIZ-RL

Overview

The ADUM226N1BRIZ-RL is a general-purpose digital isolator from Analog Devices Inc., utilizing iCoupler technology. It features two isolated channels with one reverse channel, providing robust 5000Vrms isolation voltage and an 8.3mm creepage distance. The device supports data rates up to 150Mbps with a common-mode transient immunity of 75kV/µs. Propagation delays are typically 13ns maximum, with pulse width distortion under 3ns. It operates on a single supply voltage ranging from 1.7V to 5.5V and functions within a temperature range of -40°C to 125°C. The component is housed in an 8-SOIC package.

Feature Summary

• Utilizes proprietary iCoupler magnetic coupling technology for signal isolation without external transformers.
• Provides high common-mode transient immunity to reject noise in electrically noisy environments.
• Supports bidirectional communication through integrated reverse channel capability.
• Operates across a wide industrial temperature range with fail-safe output options.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors
• Medical equipment needing reliable signal transmission across safety barriers
• Power electronics interfaces for monitoring and control circuits
• Automotive electronic systems demanding high reliability and noise immunity

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing components. Confirm RoHS3 compliance status as required by project specifications. Ensure the 8-SOIC footprint matches the PCB layout constraints. Check for moisture sensitivity level (MSL) requirements during storage and handling procedures. Validate that the operating voltage range aligns with the system power design.

Selection Notes

Select this component when high-speed data transmission is required alongside robust isolation capabilities. Consider the 150Mbps data rate for applications exceeding standard low-speed isolator limits. Evaluate the 5000Vrms isolation rating against system safety standards. Assess the 8-SOIC package size for space-constrained designs. Verify compatibility with existing logic levels and supply voltages within the 1.7V to 5.5V range.

Part Context

This part belongs to the ADuM226N series of dual-channel digital isolators. It shares architectural similarities with other iCoupler-based devices but offers specific performance characteristics tailored for general-purpose isolation needs. The series emphasizes low power consumption and high reliability compared to traditional optocoupler solutions.

Replacement Considerations

Direct substitutes include other ADUM226 variants such as ADUM226N1BRIZ or ADUM226N1BRIZ-RL depending on packaging preferences. Cross-referencing with ADuM220N or ADuM221N may be possible if pinout and electrical parameters align. Always verify functional equivalence before substitution.
