ADUM142E1WBRQZ

Digital Isolators Overview

The ADUM142E1WBRQZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 3000Vrms isolation voltage and supports data rates up to 150Mbps with unidirectional signal transmission. The device operates on a single supply voltage ranging from 1.7V to 5.5V and features low power consumption of approximately 11mA per channel. It is housed in a 16-SSOP package and meets AEC-Q100 automotive qualification standards for operation across an extended temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Utilizes proprietary iCoupler magnetic coupling technology for robust signal isolation without external transformers.
• Provides high common-mode transient immunity to protect against noise in electrically noisy environments.
• Meets AEC-Q100 automotive qualification standards for reliability in demanding applications.
• Supports wide operating supply voltages compatible with various logic families.

Digital Isolators Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems with galvanic isolation needs
• Medical equipment requiring safety-certified isolation barriers
• Power electronics gate drive circuits

Digital Isolators Procurement Notes

Verify the specific suffix QZ indicates the tape and reel packaging configuration distinct from tube variants. Confirm the E1 designation aligns with the required insulation thickness and creepage distance specifications for your application's safety clearance requirements. Ensure compatibility with the 16-SSOP footprint during PCB layout verification.

Digital Isolators Selection Notes

Select this component when four independent unidirectional channels are required within a single compact package. Consider the 150Mbps data rate limit for high-speed interface applications. Evaluate the 3000Vrms isolation rating against system voltage requirements. Compare power consumption metrics if battery-operated constraints exist.

Digital Isolators Part Context

This part belongs to the ADUM142E series of digital isolators from Analog Devices. It shares architectural similarities with other iCoupler devices but offers specific channel counts and isolation ratings tailored for general-purpose isolation tasks. The series emphasizes size reduction and performance consistency compared to traditional transformer-based solutions.

Digital Isolators Replacement Considerations

Direct substitutes include ADUM142D0BRQZ-RL7 for parameter-equivalent replacement. Verify pinout compatibility and isolation voltage ratings before swapping. Check for any differences in propagation delay or power consumption that might impact system timing or thermal design.
