ADUM1402WTRWZ33-RL

Overview

The ADUM1402WTRWZ33-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides four independent channels with two transmitters and two receivers, supporting data rates up to 90 Mb/s. The device operates on supply voltages ranging from 2.7V to 5.5V with a typical quiescent current of 44 mA per side. It features a propagation delay of 34 ns and offers 2500 Vrms isolation voltage. The component is housed in a 16-pin SOIC package and is qualified to AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for signal transmission across isolation barriers.
• Provides bidirectional signal paths with two transmitters and two receivers within a single compact package.
• Supports high common-mode transient immunity to protect against noise in electrically noisy environments.

Applications

• General multi-channel isolation
• Serial Peripheral Interface (SPI) and data converter isolation
• Industrial fieldbus isolation
• Transceiver isolation
• Automotive system isolation

Procurement Notes

Verify the specific suffix '33' against official Analog Devices documentation to confirm pinout or electrical variations compared to standard variants. Confirm availability status as this part may be subject to limited supply or obsolescence notices. Ensure the reel packaging matches system requirements. Cross-reference the AEC-Q100 qualification if automotive reliability is required.

Selection Notes

Select this component when four isolated channels are required for SPI, CAN, or general digital signals. Consider the 90 Mb/s data rate and 34 ns propagation delay for timing-sensitive designs. Verify that the 2.7V to 5.5V supply range aligns with the system's power architecture. Check if the SOIC-16 package fits the PCB layout constraints.

Part Context

This part belongs to the ADuM140x family of quad-channel digital isolators. It shares the same core iCoupler technology and functional block diagram as the ADUM1400 and ADUM1401, differing primarily in channel directionality and configuration. The family is designed to replace traditional optocouplers in space-constrained applications.

Replacement Considerations

Official substitutes include ADUM1402WTRWZ and ADUM1402ARWZ. Verify compatibility regarding package type and electrical specifications before substitution.
