ADUM141E0BRWZ-RL

Digital Isolators Overview

The ADUM141E0BRWZ-RL is a robust quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent channels with a 3:1 input-to-output configuration (three unidirectional forward channels and one reverse channel). 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 an insulation voltage of 3750 Vrms, a propagation delay of 15 ns, and a common-mode transient immunity of 75 kV/µs. It is housed in a 16-pin SOIC package and functions across an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Implements iCoupler magnetic coupling technology for galvanic isolation without external transformers.
• Provides high common-mode transient immunity to protect against noise in harsh environments.
• Supports wide supply voltage operation compatible with various logic families.
• Features low propagation delay and pulse width distortion for precise timing applications.

Digital Isolators Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing reinforced insulation barriers
• Motor control circuits with high dv/dt noise environments

Digital Isolators Procurement Notes

Verify the specific suffix 'E0' indicates the 3750 Vrms insulation rating, distinct from other variants like 'E1'. Confirm the 'WZ' suffix corresponds to the SOIC-16 wide body package. Ensure the '-RL' suffix matches the required reel packaging format for surface-mount assembly processes.

Digital Isolators Selection Notes

Select this component when a 3:1 channel configuration is required rather than symmetric 2:2 or 4:0 layouts. Choose based on the need for 3750 Vrms basic/reinforced isolation ratings. Consider the 150 Mb/s data rate limit and 15 ns propagation delay for timing-sensitive designs.

Digital Isolators Part Context

This part belongs to the ADUM141ES series of quad-channel digital isolators. It shares the same pinout and core functionality as the ADUM141E1BRWZ-RL but differs in insulation voltage rating. The series is designed for general-purpose isolation in industrial and medical applications using CMOS-compatible inputs.

Digital Isolators Replacement Considerations

ADUM141E1BRWZ-RL offers identical pinout and functionality but provides a higher insulation voltage rating of 3000 Vrms compared to the 3750 Vrms of the E0 variant. Verify if the lower rating of the E1 variant meets the safety requirements of the target application.
