ADUM1402WTRWZ33

Overview

The ADUM1402WTRWZ33 is a quad-channel digital isolator utilizing iCoupler technology, housed in a 16-lead SOIC package. It operates on a supply voltage range of 2.7 V to 5.5 V with a typical quiescent current of 44 mA per side. The device supports data rates up to 90 Mb/s and provides an isolation voltage of 2500 Vrms. It features unidirectional signal transmission with two transmitters and two receivers. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between circuits using magnetic coupling technology
• Supports high-speed digital communication with low propagation delay
• Ensures system safety through robust insulation voltage ratings
• Meets automotive reliability standards for harsh environment operation

Applications

• Automotive electronic control units requiring isolated communication
• Industrial automation systems needing reliable signal isolation
• Medical equipment demanding strict electrical safety compliance
• Power electronics interfaces for gate drive isolation

Procurement Notes

Verify the specific suffix '33' against official Analog Devices documentation to confirm pinout and packaging variations. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm availability status as distribution channels may report limited stock or restricted supply conditions. Validate that the selected variant meets all required regulatory certifications for the target application market.

Selection Notes

Select this component when four isolated channels are required for bidirectional or unidirectional data transfer. Consider the 90 Mb/s data rate capability for high-speed interface requirements. Evaluate the 2500 Vrms isolation rating against system safety standards. Check power consumption constraints as the device draws significant quiescent current compared to lower-speed alternatives.

Part Context

This part belongs to the ADuM1400/ADuM1401/ADuM1402 family of quad-channel digital isolators. These devices integrate analog and digital circuits on a monolithic CMOS substrate. The family shares common architectural features but differs in data rates and channel configurations. The ADUM1402 variant specifically targets higher speed applications within the series.

Replacement Considerations

Official substitutes include ADUM1402WSRWZ and ADUM1402WTRWZ. Verify package type and reel specifications before substitution. Ensure functional equivalence regarding data rate and isolation voltage.
