ADUM3400ARWZ-RL

Overview

The ADUM3400ARWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent channels with bidirectional data transmission capability. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 1 Mb/s. Key electrical specifications include an isolation voltage of 2500 Vrms, common-mode transient immunity of 25 kV/µs, and a typical propagation delay of 100 ns. It is housed in a 16-SOIC package and functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for signal isolation without external transformers
• Provides bidirectional data transmission across four independent channels
• Features Schmitt trigger inputs for enhanced noise immunity and clean signal regeneration
• Offers high common-mode transient immunity to ensure reliable data integrity in noisy environments

Applications

• Isolating CMOS digital I/O interfaces in industrial systems
• Protecting sensitive local ground circuits from noise and surges on data buses
• General-purpose digital isolation in measurement and control applications

Procurement Notes

Verify the specific suffix ARWZ-RL against the manufacturer's datasheet to confirm the exact package variant and reel configuration. Ensure compatibility with the required 16-SOIC footprint and check for any recent product change notices regarding manufacturing sites or material composition updates before finalizing procurement.

Selection Notes

Select this component when bidirectional communication is required across the isolation barrier. The 1 Mb/s data rate suits moderate-speed applications, while the 2500 Vrms isolation rating provides robust protection. Consider the 100 ns propagation delay for timing-sensitive designs and verify that the 16-SOIC package dimensions fit the available PCB space.

Part Context

This part belongs to the ADuM3400 series of quad-channel digital isolators. It shares the core iCoupler architecture with other variants in the family but differs in speed ratings and channel configurations. The ADUM3400 series is designed to replace traditional optocouplers and transformer-based solutions in modern electronic designs requiring galvanic isolation.
