ADUM2401CRIZ

Overview

The ADUM2401CRIZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device features bidirectional communication capability with an insulation voltage of 5000 Vrms. Key timing parameters include a propagation delay of 32 ns, rise/fall times of 3 ns, and pulse width distortion of 11.1 ns. It functions in temperatures from -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Integrates four independent digital isolation channels using monolithic air core transformer technology for high-speed CMOS signal transmission.
• Provides bidirectional data flow support with precise timing characteristics including matched channel delays and low pulse width distortion.
• Delivers robust isolation performance with 5000 Vrms insulation rating and high common-mode transient immunity.

Applications

• Industrial automation systems requiring isolated digital communication interfaces
• Medical equipment needing galvanic isolation for safety compliance
• Power electronics control circuits demanding high-speed signal transfer across potential differences

Procurement Notes

Verify the specific suffix CRIZ corresponds to the tube packaging format rather than reel variants. Confirm the bidirectional polarity specification matches system requirements, as other model variants may offer unidirectional options. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when bidirectional data transfer is required alongside high-speed isolation. Compare against unidirectional variants if directionality constraints exist. Evaluate power consumption at 57 mA operating current against system budget. Consider the 90 Mb/s rate sufficiency compared to lower-speed alternatives like the ADUM2401ARIZ.

Part Context

This part belongs to the ADUM2401 series of quad-channel digital isolators. It shares the SOIC-16 package and core iCoupler technology with siblings like the ADUM2401CRIZ-RL. Differentiation primarily lies in packaging (tube vs. reel) and potentially polarity configurations within the broader product family.

Replacement Considerations

The ADUM2401CRIZ-RL serves as a direct functional substitute differing only in reel packaging. For unidirectional applications, consider the ADUM2401ARIZ or ADUM2401CRIZ variants. Verify pinout compatibility before substituting with related models in the ADuM240x series.
