ADUM3402WARWZ-RL

Overview

The ADUM3402WARWZ-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 data transmission at speeds up to 90 Mb/s. The device provides an isolation voltage of 2500 Vrms with a propagation delay of 32 ns. It features low power consumption of 136 mA and meets AEC-Q100 automotive qualification standards. Packaged in a 16-pin SOIC format, it functions reliably across temperatures from -40°C to +105°C.

Feature Summary

• Integrates four independent bidirectional channels for high-density signal isolation
• Employs on-chip transformer-based magnetic coupling for robust noise immunity
• Automotive qualified under AEC-Q100 standards for enhanced reliability
• Supports wide operating temperature ranges suitable for harsh environments

Applications

• Automotive electronic control units requiring certified isolation
• Industrial communication interfaces such as CAN and LIN buses
• Motor drive systems needing galvanic separation between control and power stages
• Medical equipment requiring patient isolation protection

Procurement Notes

Verify the specific suffix 'W' indicates automotive grade qualification when sourcing. Confirm the '-RL' suffix denotes reel packaging for automated assembly lines. Ensure compatibility with existing PCB footprints for the 16-SOIC package. Check current availability status as distribution may be limited or subject to factory orders. Validate that the 90 Mb/s speed rating aligns with system timing requirements.

Selection Notes

Select this component when automotive certification is mandatory for digital isolation applications. Compare power consumption against non-automotive variants if cost is a primary constraint. Consider the 90 Mb/s data rate capability for high-speed serial communication needs. Evaluate the 2500 Vrms isolation barrier against system safety regulations. Assess the 16-SOIC footprint constraints against available board space.

Part Context

This part belongs to the ADUM3402 series of quad-channel digital isolators. It shares architectural similarities with the ADUM3400 and ADUM3401 models but offers higher data rates. The series utilizes Analog Devices' proprietary iCoupler technology. It serves as a replacement for traditional optocouplers in modern designs.

Replacement Considerations

The ADUM3402CRWZ is a commercial grade alternative without automotive qualification. The ADUM3402BRWZ offers similar functionality but may differ in specific electrical parameters. Verify pinout compatibility before substituting any variant within the ADUM3402 family.
