ADUM142D1BRQZ

Digital Isolators Overview

The ADUM142D1BRQZ is a robust quad-channel digital isolator utilizing Analog Devices iCoupler technology. It features a 2:2 channel configuration with unidirectional data flow. The device supports data rates up to 150 Mb/s and offers a common-mode transient immunity of 75 kV/µs. It operates on supply voltages between 1.8 V and 5 V, drawing 11 mA of operating current. Key electrical parameters include a propagation delay of 15 ns, rise/fall times of 2.5 ns, and a pulse width distortion of less than 0.5 ns. It provides 3000 Vrms isolation voltage and functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four independent isolation channels using monolithic air core transformer technology for high-speed signal transmission.
• Provides robust electromagnetic interference rejection with high common-mode transient immunity capabilities.
• Supports standard logic interfaces including SPI communication protocols across isolated boundaries.

Digital Isolators Applications

• Industrial control systems requiring galvanic isolation
• Automotive electronic subsystems
• Medical equipment signal isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'QZ' against official Analog Devices documentation to confirm RoHS compliance and lead-free status. Ensure the 16-SSOP package dimensions match your PCB footprint requirements. Confirm that the 3000 Vrms isolation rating meets your system's safety standards. Check for any specific handling instructions related to moisture sensitivity level indicated in the datasheet.

Digital Isolators Selection Notes

Select this component when bidirectional isolation is not required, as it is strictly unidirectional. Choose the 2:2 channel variant if two input and two output channels are sufficient for the application. Consider the 150 Mbps speed limit for high-frequency applications. Evaluate the 16-SSOP package size against available board space constraints compared to SOIC alternatives.

Digital Isolators Part Context

This part belongs to the ADUM142D series of digital isolators from Analog Devices. It shares the same core iCoupler technology family as other devices in the series but differs in channel count and directionality. The 'QZ' suffix typically denotes a specific packaging or environmental compliance variation within the broader ADUM142 product line.

Digital Isolators Replacement Considerations

The ADUM142D1BRZ is a pin-compatible alternative in the same series. Verify if the package type (SSOP vs SOIC) and specific suffix requirements align with your design needs before substituting.
