ADUM141D1BRQZ-RL7

Digital Isolators Overview

The ADUM141D1BRQZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four channels configured as three unidirectional forward channels and one reverse channel. The device supports data rates up to 150 Mb/s with a propagation delay of 15 ns and rise/fall times of 2.5 ns. It operates on supply voltages between 1.7 V and 5.5 V, drawing 11.4 mA. Key isolation specifications include 3000 Vrms insulation voltage and 75 kV/µs common-mode transient immunity. It is housed in a 16-pin QSOP package and functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Provides robust noise immunity with 75 kV/µs common-mode transient immunity rating.
• Supports flexible data flow configurations with three unidirectional forward channels and one reverse channel.
• Operates across a wide industrial temperature range without requiring external shutdown control.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal interfaces
• Inverter gate drive circuits
• Isolated communication bus implementations

Digital Isolators Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'D1' indicates the 3:1 channel configuration distinct from other variants in the ADUM141 series. Check current availability status as supply constraints may affect lead times. Ensure storage conditions account for moisture sensitivity levels specified in the datasheet prior to reflow soldering.

Digital Isolators Selection Notes

Select this variant when a 3:1 directional isolation topology is required rather than symmetric bidirectional channels. Compare against the ADUM141D0BRQZ-RL7 if a 4:0 configuration is needed instead. Ensure the 150 Mbps data rate meets system timing requirements. Verify that the 3000 Vrms isolation rating satisfies safety standards for the target application environment.

Digital Isolators Part Context

This component belongs to the ADuM141 family of quad-channel digital isolators. It represents an evolution of earlier iCoupler designs, offering improved performance metrics such as higher common-mode transient immunity compared to legacy models. The BRQZ suffix denotes the specific tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Digital Isolators Replacement Considerations

Direct substitutes include ADUM141D0BRQZ-RL7 for 4:0 channel configurations or ADUM141D1BRQZ (non-RL7) for cut-tape packaging. Cross-family alternatives like ADuM1411 require verification of pinout compatibility and isolation voltage ratings.
