ADUM140E1WBRWZ

Overview

The ADUM140E1WBRWZ is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mbps and an isolation voltage of 3750 Vrms. The device operates within a supply voltage range of 1.7V to 5.5V and supports a maximum propagation delay of 15 ns. Packaged in a 16-SOIC wide body, it is AEC-Q100 qualified for automotive applications and functions across a temperature range of -40°C to 125°C.

Feature Summary

• Integrates four independent unidirectional signal paths using monolithic air core transformer technology for robust magnetic coupling.
• Provides high common-mode transient immunity to ensure reliable signal integrity in electrically noisy environments.
• Supports bidirectional level translation between 3V and 5V logic domains without requiring external components.
• Delivers precise timing characteristics with minimal pulse width distortion and tight channel-to-channel matching.

Applications

• General-purpose multichannel isolation
• SPI interface and data converter isolation
• RS-232/RS-422/RS-485 transceiver isolation
• Industrial field bus isolation
• Automotive systems

Procurement Notes

Verify the specific suffix WBRWZ corresponds to the SOIC-16 wide body package and reel packaging configuration. Confirm that the E1 designation aligns with the required insulation rating and automotive qualification standards for your target application environment before finalizing procurement.

Selection Notes

Select this component when four isolated channels are required for high-speed digital signals up to 150 Mbps. It is suitable for designs needing strong common-mode noise rejection and precise timing synchronization. Ensure the system voltage requirements fall within the 1.7V to 5.5V operating range and that the thermal environment stays within the specified industrial temperature limits.

Part Context

This part belongs to the ADuM140 series of quad-channel digital isolators based on iCoupler technology. It serves as a modern replacement for traditional optocouplers, offering superior performance in speed, power consumption, and size while maintaining high isolation reliability for critical signal transmission.

Replacement Considerations

Public confirmed substitute part numbers include ADUM140E0WBRWZ and ADUM140E1BRWZ. Verify compatibility regarding package dimensions and electrical specifications before substitution.
