ADUM1400ARWZ

Overview

The ADUM1400ARWZ is a quad-channel digital isolator utilizing Analog Devices iCoupler technology. It provides four independent channels with a 2/2 input/output configuration. The device operates on a supply voltage range of 2.7V to 5.5V and features a maximum propagation delay of 100ns per channel. It supports data rates up to 1Mbps and offers a common-mode transient immunity (CMTI) of 25kV/µs. The isolation rating is 2500Vrms, and it functions within an operating temperature range of -40°C to 125°C.

Feature Summary

• Integrates high-speed CMOS logic with single-chip air-core transformer technology for signal isolation
• Provides bidirectional communication capability across four isolated channels
• Delivers robust common-mode transient immunity to protect against noise interference

Applications

• General-purpose signal isolation in industrial automation systems
• Isolation barriers in process control applications
• Digital communication interface isolation in embedded systems

Procurement Notes

Verify the specific suffix 'ARWZ-RL' against official Analog Devices documentation to confirm reel packaging and RoHS compliance status. Ensure the component matches the active product lifecycle stage indicated in current datasheets. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when four isolated bidirectional channels are required within a single package. It is suitable for designs needing 2500Vrms isolation with low power consumption compared to optical alternatives. Consider the 16-SOIC package constraints and the 1Mbps data rate limit when evaluating system timing requirements.

Part Context

This component belongs to the ADuM1400 series of quad-channel digital isolators from Analog Devices. The series utilizes proprietary iCoupler technology to replace traditional optocouplers. The ADUM1400 variant specifically offers a symmetric 2-input/2-output channel arrangement for versatile circuit integration.
