ADUM1400BRWZ-RL

Overview

The ADUM1400BRWZ-RL is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It provides bidirectional signal isolation with a rated voltage of 2500Vrms and supports data rates up to 90Mbps. The device operates on a supply voltage range of 2.7V to 5.5V, featuring a typical propagation delay of 34ns and rise/fall times of approximately 3ns. Designed for surface mount installation in a 16-SOIC package, it ensures high common-mode transient immunity of 25kV/µs across all four channels.

Feature Summary

• Integrates high-speed CMOS logic with single-chip air-core transformer technology for robust magnetic signal coupling.
• Provides bidirectional data transmission capability across four independent isolated channels.
• Delivers high common-mode transient immunity to mitigate noise interference in electrically noisy environments.

Applications

• Industrial automation systems requiring galvanic isolation between control and power stages
• Medical equipment interfaces needing certified safety isolation barriers
• Power metering circuits for accurate signal measurement across potential differences

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm the component status as limited supply or obsolete depending on current distributor inventory. Ensure compatibility with RoHS3 standards if required by project specifications. Cross-reference the exact part number against manufacturer databases to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component for applications requiring bidirectional communication over isolated barriers. Compare performance metrics such as propagation delay and data rate against unidirectional alternatives like the ADUM1402 series. Evaluate power consumption requirements relative to the 70mA operating current. Consider the SOIC-16 footprint constraints during PCB layout design to ensure adequate clearance for the 2500Vrms isolation rating.

Part Context

This component belongs to the ADuM1400 family of quad-channel digital isolators. It represents an evolution in iCoupler technology, offering higher data throughput compared to earlier generations. The family is designed to replace traditional optocouplers in space-constrained designs while providing superior reliability and lower power consumption characteristics.

Replacement Considerations

Publicly confirmed substitute part numbers include ADUM1400WSRWZ and ADUM1400WTRWZ. Verify pinout compatibility and electrical parameter alignment before substitution. Note that some variants may differ in packaging type or temperature range specifications.
