ADUM142E1BRZ-RL7

Digital Isolators Overview

The ADUM142E1BRZ-RL7 is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mb/s and a propagation delay of 13 ns. The device operates on a supply voltage range of 1.8 V to 5 V, consuming 11 mA of quiescent current. It provides 3000 Vrms isolation voltage and supports a common-mode transient immunity of 75 kV/µs. Housed in a 16-SOIC package, it functions within an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four independent unidirectional signal paths for robust channel separation.
• Employs monolithic air-core transformer technology for high-speed magnetic coupling.
• Delivers high common-mode transient immunity to maintain signal integrity in noisy environments.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal processing interfaces
• Automotive electronic control unit communication

Digital Isolators Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the E1 designation aligns with the required 3000 Vrms isolation rating for your circuit design. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check regional availability as distribution may be restricted in certain areas.

Digital Isolators Selection Notes

Select this component for applications demanding high-speed data transmission across isolated boundaries. The 150 Mb/s rate suits standard industrial protocols. Consider the 16-SOIC package size for space-constrained designs. Verify that the 1.8 V to 5 V supply range matches the logic levels of the connected microcontrollers or processors.

Digital Isolators Part Context

This part belongs to the ADUM142E series of general-purpose digital isolators from Analog Devices. It shares the iCoupler architecture with other members like the ADUM140 and ADUM142D variants. The primary distinction lies in the specific isolation ratings and channel configurations offered within the family.
