ADUM4400BRWZ

Overview

The ADUM4400BRWZ is a quad-channel digital isolator utilizing iCoupler technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 10 Mb/s. The device provides 5000 Vrms isolation voltage with enhanced ESD protection. Key electrical parameters include a propagation delay of 32 ns, rise/fall times of 3 ns, and a pulse width distortion of 100 ns. It functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Provides four independent bidirectional or unidirectional signal channels for high-density isolation.
• Integrates on-chip dual wound transformers for magnetic coupling without external components.
• Features enhanced electrostatic discharge (ESD) protection capabilities.
• Maintains signal integrity through low jitter performance in noisy environments.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal processing interfaces
• Power electronics control circuit isolation
• Instrumentation and measurement devices

Procurement Notes

Verify the specific suffix BRWZ against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with required isolation standards and thermal management specifications before integration. Cross-reference datasheet revisions for any updates to pinout or electrical characteristics.

Selection Notes

Select this component when four isolated channels are required within a single package. Consider the 10 Mb/s data rate limit for high-speed applications. Evaluate the 5000 Vrms isolation rating against system safety requirements. Compare power consumption metrics if battery-operated constraints exist.

Part Context

This part belongs to the ADuM440x family of digital isolators from Analog Devices. These devices replace traditional optocouplers by offering superior performance, smaller size, and greater reliability. The family includes variants with different channel counts and data rates to suit various isolation needs.

Replacement Considerations

Check for ADUM4401 or ADUM4402 equivalents if higher data rates or different channel configurations are needed. Verify pin-to-pin compatibility with existing designs before substitution. Consult official replacement guides for updated component recommendations.
