ADUM2401CRWZ-RL

Overview

The ADUM2401CRWZ-RL 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 bidirectional communication at data rates up to 90 Mbps (NRZ). The device provides 5000 Vrms isolation voltage and features a propagation delay of 32 ns with rise/fall times of 3 ns. It is housed in a 16-SOIC package, rated for operation between -40°C and +105°C, and draws 57 mA of operating current.

Feature Summary

• Bidirectional communication capability with integrated 3 V/5 V level translation
• High common-mode transient immunity (CMTI) of 25 kV/µs
• Precision timing characteristics including maximum 2 ns pulse width distortion and channel-to-channel matching

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety barriers
• Power metering and energy management interfaces

Procurement Notes

Verify the specific suffix 'CRWZ' confirms the wide-body SOIC-16 package variant rather than the standard narrow body. Confirm the '-RL' designation indicates reel packaging. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this component when bidirectional signal transfer is required across isolated boundaries. The 90 Mbps rate suits moderate-speed digital interfaces. The wide operating temperature range supports harsh environments. Compare against unidirectional variants like the ADUM2402 if directionality constraints exist. Verify that the 5000 Vrms insulation rating aligns with system safety standards.

Part Context

This part belongs to the ADuM240x family of quad-channel digital isolators based on iCoupler technology. It shares architectural similarities with the ADUM2400 and ADUM2402 but differs in channel directionality and speed specifications. The CRWZ suffix denotes the specific physical package dimensions suitable for higher isolation creepage distances compared to narrower packages.

Replacement Considerations

The ADUM2401CRIZ-RL serves as a pin-compatible alternative using the standard SOIC-16 package instead of the wide-body version. Both share identical electrical performance metrics including 90 Mbps speed and 5000 Vrms isolation. Verify mechanical fitment differences due to package width variations before substitution.
