ADUM3400BRWZ-RL

Overview

The ADuM3400BRWZ-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides bidirectional signal isolation with a data rate of 10 Mb/s and a common-mode transient immunity (CMTI) of 25 kV/µs. The device operates on a supply voltage range of 2.7 V to 5.5 V, drawing typical operating currents of 3 mA and 9 mA for the respective sides. Key timing parameters include a propagation delay of 50 ns and rise/fall times of 3 ns. It features a 2500 Vrms isolation rating and functions within an industrial temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent channels for high-density signal isolation
• Employs iCoupler magnetic coupling for robust galvanic isolation
• Supports bidirectional data transmission across isolated boundaries

Applications

• Industrial automation control systems
• Medical equipment signal interfaces
• Power electronics gate drive circuits

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific BRWZ suffix matches design requirements, as it denotes the commercial temperature grade and reel packaging format. Request original manufacturer documentation to validate lot traceability and RoHS compliance status before finalizing procurement orders.

Selection Notes

Select this component when bidirectional communication is required between isolated domains. The 10 Mb/s speed suits moderate-rate applications, while the 2500 Vrms rating ensures safety compliance. Ensure the 16-SOIC package fits the PCB layout constraints and that the 2.7 V to 5.5 V supply range aligns with the system power architecture.

Part Context

This part belongs to the ADuM3400 series, which includes variants like the CRWZ-RL offering higher speeds. The BRWZ designation specifically indicates the commercial temperature performance tier. It shares the same physical footprint and pinout with other members of the family, facilitating design flexibility across different speed and temperature requirements.

Replacement Considerations

The ADUM3400CRWZ-RL serves as a verified substitute, offering identical pinouts but with enhanced 90 Mbps data rates. Designers must verify that the increased speed does not introduce noise issues in sensitive analog environments. Other family members like the ADUM3402BRWZ offer unidirectional options if bidirectional capability is unnecessary.
