ADUM3401TRWZ-EP-RL

Overview

The ADUM3401TRWZ-EP-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 provides 2500 Vrms isolation voltage. The device features bidirectional channels with a data rate of 90 Mb/s and a propagation delay of 32 ns. It is housed in a 16-pin SOIC package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for high-speed signal transmission
• Provides enhanced system-level ESD reliability
• Features bidirectional channel configuration for flexible interface design

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Automotive electronic control units (ECUs)

Procurement Notes

Verify the specific suffix 'EP' indicates enhanced product specifications or military-grade screening when sourcing. Confirm availability status as distribution listings may indicate limited stock or special order requirements. Ensure the reel packaging matches automated assembly needs. Cross-reference the datasheet revision date to confirm current electrical characteristics before finalizing procurement.

Selection Notes

Select this component when bidirectional communication is required across the isolation barrier. The 90 Mb/s data rate suits moderate-speed industrial protocols. Verify that the 2500 Vrms isolation rating meets the safety standards of the target application. Consider the 16-SOIC package dimensions for PCB layout constraints compared to wider body options.

Part Context

This part belongs to the ADUM3401 series of quad-channel digital isolators. It shares the core iCoupler architecture with other variants but differs in channel directionality and specific performance metrics. The EP suffix typically denotes enhanced processing or qualification levels within the Analog Devices portfolio.

Replacement Considerations

Direct substitutes include ADUM3401ARWZ-RL and ADUM3401WARWZ-RL. These alternatives share the same package and basic functionality but may differ in channel directionality or specific qualification standards. Verify pin compatibility and isolation ratings before substitution.
