ADUM240D1BRIZ

Overview

The ADUM240D1BRIZ is a robust quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four unidirectional signal channels with a data rate of 150 Mb/s and a maximum propagation delay of 7.2 ns. The device offers 5000 Vrms isolation voltage and operates within a supply voltage range of 1.7 V to 5.5 V. It features a common-mode transient immunity of 75 kV/µs and functions reliably across an extended temperature range of -40°C to +125°C. Packaged in a 16-lead SOIC, it supports high-speed communication in noisy environments.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for robust signal transmission
• Provides four unidirectional channels for versatile interface isolation
• Ensures safe system performance in harsh and unpredictable environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation

Procurement Notes

Verify the specific suffix D1 against official Analog Devices documentation to confirm channel configuration and pinout compatibility. Ensure the 16-SOIC package dimensions match your PCB footprint requirements. Confirm that the operating temperature range meets your environmental specifications before finalizing procurement decisions.

Selection Notes

Select this component when high-speed data rates up to 150 Mb/s are required alongside strong isolation capabilities. The wide supply voltage range allows flexibility in power design. Consider the 75 kV/µs CMTI rating for applications with significant noise or rapid voltage transitions on isolated boundaries.
