ADUM142E1BRQZ-RL7

Digital Isolators Overview

The ADUM142E1BRQZ-RL7 is a quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent channels with a 2:2 configuration and unidirectional signal transmission. The device operates within a supply voltage range of 1.7 V to 5.5 V and supports data rates up to 150 Mb/s. Key electrical specifications include a 3000 Vrms isolation voltage, a common mode transient immunity (CMTI) of 75 kV/µs, and a propagation delay of 15 ns. It functions across an extended temperature range of -40°C to +125°C and is housed in a 16-pin QSOP package.

Digital Isolators Feature Summary

• Integrates four isolated channels using monolithic air core transformer technology for robust signal transmission.
• Provides high common mode transient immunity to withstand rapid voltage changes across the isolation barrier.
• Supports wide operating supply voltages compatible with various logic families.
• Certified for automotive applications under AEC-Q100 standards.

Digital Isolators Applications

• Automotive electronic control units requiring certified isolation
• Industrial communication interfaces such as RS-485 and CAN bus
• Medical equipment requiring reinforced safety isolation
• Power monitoring systems with high voltage sensing

Digital Isolators Procurement Notes

Verify the specific suffix QZ indicates the QSOP-16 package variant distinct from other pinouts. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current availability as distribution may be limited or subject to factory special orders. Ensure the reel packaging format matches automated assembly requirements. Validate that the E1 designation aligns with the required isolation voltage rating for the target application.

Digital Isolators Selection Notes

Select this component when high-speed bidirectional data transfer is not required due to its unidirectional channel design. Choose this part over lower-rated variants if 3000 Vrms isolation is mandatory for safety standards. Consider the 150 Mb/s data rate limit against system timing requirements. Evaluate the 16-pin QSOP footprint against PCB space constraints compared to SOIC alternatives.

Digital Isolators Part Context

This device belongs to the ADUM142E series of iCoupler digital isolators. It shares architectural similarities with the ADUM142D series but offers enhanced performance metrics including higher CMTI and wider temperature ranges. The product line utilizes CMOS technology integrated with on-chip transformers to replace traditional optocouplers in high-reliability designs.

Digital Isolators Replacement Considerations

The ADUM142D0BRQZ-RL7 is documented as a parameter-equivalent substitute. Verify package compatibility and specific electrical tolerances before substitution. Other family members like the ADUM142E1WBRQZ offer different physical footprints.
