ADUM142E1WBRWZ-RL

Digital Isolators Overview

The ADUM142E1WBRWZ-RL is a quad digital isolator utilizing iCoupler magnetic coupling technology. It provides four independent 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 unidirectional signal transmission. Key electrical specifications include a maximum propagation delay of 15 ns, typical rise and fall times of 2.5 ns, and a minimum common-mode transient immunity of 75 kV/µs. It is housed in a 16-SOIC package and is AEC-Q100 qualified for automotive applications.

Digital Isolators Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology
• Supports high-speed data transmission up to 150 Mbps per channel
• Provides robust protection against common-mode transients with high immunity ratings
• Certified for automotive reliability under the AEC-Q100 standard

Digital Isolators Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interfaces such as CAN and RS-485
• General-purpose digital isolation in mixed-signal systems
• SPI bus isolation for sensor and peripheral interfacing

Digital Isolators Procurement Notes

Verify the specific suffix WBRWZ-RL to confirm the wide-body SOIC package and reel packaging configuration. Ensure the E1 variant matches the required isolation voltage and temperature grade for the target application. Cross-reference the manufacturer datasheet for pinout compatibility and thermal management requirements before integration.

Digital Isolators Selection Notes

Select this component when four independent unidirectional isolation channels are required at 150 Mbps speeds. The 3750 Vrms isolation rating suits applications needing moderate isolation barriers. Consider the 1.7V to 5.5V supply range for compatibility with various logic levels. The AEC-Q100 qualification makes it suitable for automotive environments where reliability standards are strict.

Digital Isolators Part Context

This part belongs to the ADUM142 series of iCoupler digital isolators from Analog Devices. It shares the core magnetic coupling architecture with other members like the ADUM141 and ADUM142 variants but differs in channel count, directionality, and isolation voltage specifications. The wide-body package distinguishes it from standard SOIC versions.

Digital Isolators Replacement Considerations

ADUM142E1WBRQZ is a parameter-equivalent alternative available in a 16-SSOP package.
