ADUM140D0BRWZ

Overview

The ADUM140D0BRWZ is a quad-channel digital isolator utilizing iCoupler technology. It provides 3750 Vrms isolation with a data rate of 150 Mbps and 75 kV/µs common-mode transient immunity. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V. It features unidirectional signal transmission across four channels within a 16-pin SOIC package.

Feature Summary

• Robust magnetic coupling isolation for high-speed data transmission
• High common-mode transient immunity for noise rejection
• Wide operating temperature range for industrial environments

Applications

• Industrial automation systems
• Medical equipment signal isolation
• Power metering applications

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm availability status as distribution channels may report limited stock or end-of-life conditions. Ensure the ordering part number matches the required package width and thermal specifications for your design.

Selection Notes

Select this component when high-speed bidirectional communication is not required, as it supports only unidirectional channels. Consider the 16-SOIC package dimensions for PCB layout constraints. Evaluate the 150 Mbps data rate against system timing requirements to ensure signal integrity across the isolation barrier.

Part Context

This part belongs to the ADuM140 series of robust digital isolators. It shares architectural similarities with other variants in the family but differs in channel configuration and isolation voltage ratings. The series utilizes proprietary CMOS technology to integrate passive components onto the silicon die.

Replacement Considerations

Official substitutes include ADUM140D0BRZ and ADUM140D0BRZ-RL7. Verify compatibility regarding package dimensions and electrical parameters before substitution.
