ADUM141D1BRQZ

Digital Isolators Overview

The ADuM141D1BRQZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It features four channels with three unidirectional forward paths and one reverse path, supporting data rates up to 150 Mb/s. The device operates on a supply voltage range of 1.7 V to 5.5 V with a typical quiescent current of 11.4 mA per side. It provides an isolation voltage of 3750 Vrms and a common-mode transient immunity of 75 kV/µs. Packaged in a 16-lead SSOP (0.154 inch width), it 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 electrical isolation with a rated insulation voltage of 3750 Vrms and high common-mode transient immunity.
• Supports flexible logic interfaces with a wide supply voltage range from 1.7 V to 5.5 V.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripherals.
• Medical equipment needing reliable signal isolation for safety compliance.
• Power electronics control circuits interfacing low-voltage logic with high-voltage power stages.

Digital Isolators Procurement Notes

Verify the specific suffix BRQZ confirms the 16-lead SSOP package and reel/cut-tape availability. Confirm the D1 variant designation matches the required 3:1 channel configuration and 3750 Vrms isolation rating against system specifications. Check RoHS compliance status and humidity sensitivity level before storage planning.

Digital Isolators Selection Notes

Select this component when a quad-channel isolator with asymmetric 3:1 directionality is required. Ensure the 150 Mb/s data rate meets the application's timing constraints. Verify that the 16-SSOP footprint fits the PCB layout and that the 1.7 V to 5.5 V supply range aligns with the system's voltage rails.

Digital Isolators Part Context

This part belongs to the ADuM141D family of digital isolators from Analog Devices. These devices replace traditional optocouplers by offering superior performance in speed, size, and reliability. The family utilizes silicon dioxide and copper coil technology to create compact, high-performance isolation barriers.

Digital Isolators Replacement Considerations

The ADUM141D0BRQZ is a related variant but offers lower isolation voltage (3000 Vrms). Direct substitution requires verifying if the reduced isolation rating meets the application's safety requirements. Other ADuM141x variants may differ in channel count or package type.
