ADUM4400BRIZ-RL

Overview

The ADUM4400BRIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for galvanic isolation. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 10 Mb/s. The device features a propagation delay of 32 ns and draws a typical operating current of 830 µA. It provides an insulation voltage rating of 5000 Vrms and is housed in a SOIC-16 package with unidirectional channel polarity.

Feature Summary

• Provides four independent channels of digital signal isolation using magnetic coupling technology
• Supports high-speed data transmission with a maximum rate of 10 Mb/s per channel
• Features low power consumption suitable for energy-efficient system designs
• Ensures robust electrical isolation with a 5000 Vrms insulation voltage rating

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for safety compliance
• Power electronics control circuits with high-voltage noise environments
• Automotive electronic control units (ECUs) with strict isolation requirements

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when ordering. Confirm that the SOIC-16 package dimensions match your PCB footprint requirements. Ensure the 5000 Vrms isolation rating meets your application's safety standards. Check for any regional distribution restrictions or limited availability status before finalizing procurement plans.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required at moderate data speeds. The 10 Mb/s limit distinguishes it from higher-speed variants. Consider the 830 µA quiescent current for battery-operated applications. Verify that the SOIC-16 package is compatible with your assembly process and thermal management strategy.

Part Context

This part belongs to the ADUM4400 family of digital isolators designed for general-purpose isolation tasks. It complements other ADUM series components by offering a balance between speed, power, and channel count. The magnetic coupling architecture differentiates it from capacitive or optical isolators in the same product line.

Replacement Considerations

Check for direct pin-compatible substitutes within the ADUM4400 series. Verify if alternative packages like WSOIC are available for similar performance. Ensure any replacement maintains the 5000 Vrms isolation rating and 10 Mb/s data rate specifications.
