ADUM140E0BRZ-RL7

Overview

The ADUM140E0BRZ-RL7 is a robust quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mb/s and a propagation delay of 15 ns. The device operates on a supply voltage range of 1.8 V to 5 V and provides an isolation voltage of 3000 Vrms. It exhibits a common-mode transient immunity of 75 kV/µs and functions within a temperature range of -40°C to +125°C. Packaged in a 16-SOIC format, it supports Reel, Cut Tape, and MouseReel configurations.

Feature Summary

• Integrates four independent unidirectional signal paths using proprietary magnetic coupling technology for galvanic isolation.
• Delivers high-speed digital communication capabilities with a maximum data rate of 150 Mb/s per channel.
• Provides robust noise immunity against high-frequency transients with a minimum common-mode transient immunity rating.

Applications

• Industrial process control systems requiring isolated sensor interfaces
• Medical equipment needing reliable patient isolation barriers
• Power management circuits involving isolated gate drive signals

Procurement Notes

Verify the specific suffix 'RL7' corresponds to the required tape-and-reel packaging configuration for automated assembly lines. Confirm that the 16-SOIC package dimensions align with the target PCB footprint and soldering profile requirements. Ensure the component meets RoHS compliance standards relevant to the destination market regulations before finalizing procurement orders.

Selection Notes
