ADUM140E1WBRWZ-RL

Overview

The ADUM140E1WBRWZ-RL is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a 3:1 input-to-output configuration, supporting data rates up to 150 Mbps. The device provides an isolation voltage of 3750 Vrms and a minimum common-mode transient immunity of 75 kV/µs. Operating on a supply voltage range of 1.7 V to 5.5 V, it exhibits a typical propagation delay of 13 ns and rise/fall times of 2.5 ns. Packaged in a wide 16-SOIC (7.50 mm) format, it supports industrial temperatures from -40°C to +125°C.

Feature Summary

• Integrates four independent unidirectional signal paths within a single package for efficient board space utilization.
• Employs proprietary iCoupler magnetic coupling technology to provide galvanic isolation without requiring external transformer drivers.
• Delivers high-speed signal transmission capabilities suitable for demanding communication protocols.
• Ensures robust noise immunity against rapid voltage transients across the isolation barrier.

Applications

• Industrial automation systems requiring reliable signal isolation between control and field devices.
• Medical equipment interfaces necessitating strict safety compliance and patient isolation.
• Power electronics gate drive circuits for isolated control of switching elements.
• General-purpose digital isolation in instrumentation and measurement applications.

Procurement Notes

Verify that the specific suffix matches the required wide SOIC package dimensions and reel specifications. Confirm that the component meets the necessary automotive or industrial qualification standards if applicable to the target environment. Ensure compatibility with the system's logic voltage levels and isolation requirements before finalizing the procurement order.

Selection Notes

Select this component when a quad-channel solution with unidirectional data flow is required. The wide SOIC package facilitates easier PCB layout compared to narrower variants. Consider the 150 Mbps data rate and 75 kV/µs CMTI as key differentiators for noisy environments. Evaluate power consumption constraints relative to the 1.7 V to 5.5 V operating range.

Part Context

This part belongs to the ADUM140 series of digital isolators, which are designed to replace traditional optocouplers in modern designs. The series offers superior performance in terms of speed, reliability, and size reduction. The ADUM140E1 variant specifically targets applications needing robust isolation with standardized pinouts and packaging options.
