ADUM1400BRWZ

Overview

The ADUM1400BRWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling 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 an isolation voltage of 2500 Vrms with a common-mode transient immunity of 25 kV/µs. Typical propagation delay is 32 ns, with rise and fall times of 3 ns. It functions across an operating temperature range of -40°C to +105°C and is housed in a 16-lead SOIC package.

Feature Summary

• Integrates four independent bidirectional channels for signal isolation using proprietary iCoupler technology.
• Provides high-speed data transmission capabilities suitable for demanding industrial communication protocols.
• Ensures robust electrical isolation between circuits with significant common-mode transient immunity.

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment signal interfaces
• Power management circuit monitoring
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'BRWZ' against official Analog Devices documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with existing board layouts regarding the 16-SOIC footprint. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when four isolated channels are required within a single package. Consider the 10 Mb/s data rate limit for application speed requirements. Evaluate the 2500 Vrms isolation rating against system safety standards. Compare power consumption metrics with alternative solutions if energy efficiency is critical.

Part Context

This part belongs to the ADuM1400 series of quad-channel digital isolators from Analog Devices. It shares the same core architecture as variants like ADUM1401 and ADUM1402 but differs in channel directionality and specific performance characteristics. The series represents a transition from traditional transformer-based isolation to integrated magnetic coupling solutions.

Replacement Considerations

Publicly confirmed substitute part numbers include ADUM1402BRWZ. Verify functional equivalence and pinout compatibility before substitution. Check datasheet specifications for any differences in propagation delay or isolation ratings that may impact system performance.
