ADUM1400WSRWZ-RL

Overview

The ADUM1400WSRWZ-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and provides 2500 Vrms isolation voltage. The device supports data rates up to 90 Mb/s with a typical propagation delay of 100 ns. It features four unidirectional channels in a 16-pin SOIC_W package, designed for robust signal transmission across isolated boundaries.

Feature Summary

• Integrates four independent digital isolation channels within a compact surface-mount package
• Employs iCoupler technology to eliminate the need for external discrete components or optical elements
• Provides high common-mode transient immunity for reliable operation in electrically noisy environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal interface circuits
• Power metering and energy management applications

Procurement Notes

Verify the specific suffix 'W' indicates wide operating temperature range capabilities and 'SRWZ-RL' denotes reel packaging configuration. Confirm AEC-Q100 qualification status if automotive compliance is required. Ensure compatibility with standard SOIC-16 footprint dimensions during PCB layout verification.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are needed at moderate data speeds. Compare against higher-speed variants like the ADUM140D series if greater throughput is necessary. Consider power consumption differences between channel configurations and supply voltage requirements relative to system constraints.

Part Context

This part belongs to the ADUM1400 family of general-purpose digital isolators. It shares architectural similarities with other members but differs in channel count and speed specifications. The W suffix typically signifies extended temperature performance compared to standard industrial grade parts.

Replacement Considerations

Direct substitutes include ADUM1400ARWZ for tube packaging or ADUM1400WTRWZ for tape-and-reel options with similar electrical characteristics. Verify pinout compatibility and thermal performance before swapping packages.
