ADUM4402CRWZ

Overview

The ADUM4402CRWZ 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 provides 5000 Vrms isolation voltage and features a typical propagation delay of 32 ns with rise and fall times of 3 ns. It is housed in a 16-lead SOIC package and functions bidirectionally across four channels.

Feature Summary

• Integrates four independent bidirectional signal paths using proprietary iCoupler magnetic coupling technology for high-speed data transmission.
• Provides robust electrical isolation rated at 5000 Vrms between input and output sides.
• Supports data rates up to 90 Mb/s with low propagation delay and minimal pulse width distortion.

Applications

• General-purpose digital isolation in industrial communication systems
• Isolating microcontroller interfaces in noisy environments
• Signal isolation in medical equipment requiring enhanced safety standards

Procurement Notes

Verify the specific suffix CRWZ against the manufacturer's current datasheet to confirm pinout and packaging details. Confirm availability status as distribution listings may indicate limited stock or discontinuation. Ensure the component meets RoHS compliance requirements for your target market before finalizing procurement orders.

Selection Notes

Select this component when bidirectional isolation is required for multiple digital signals simultaneously. Compare against unidirectional variants like the ADUM4400 if directionality constraints exist. Consider the integrated nature of the isolator versus discrete solutions for board space optimization and consistent performance characteristics.

Part Context

This part belongs to the ADUM4402 series of quad-channel digital isolators. It shares the SOIC-16 footprint with related models but differs in channel count and isolation voltage ratings compared to single or dual-channel counterparts in the broader iCoupler family.

Replacement Considerations

The ADUM4402CRWZ-RL is a reel-packaged version of the same functional component. Verify that the tape-and-reel format aligns with automated assembly requirements without altering electrical specifications.
