ADUM241D1BRIZ-RL

Overview

The ADUM241D1BRIZ-RL is a general-purpose digital isolator from Analog Devices Inc., featuring four isolated channels in a 16-SOIC package. It provides 5000 Vrms isolation with a data rate of 150 Mb/s and a propagation delay of 7.2 ns. The device operates on a single supply voltage ranging from 1.7V to 5.5V, drawing 11.4 mA of quiescent current. It supports unidirectional signal transmission with a 3:1 channel configuration and offers a common-mode transient immunity of 75 kV/µs. The component functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for robust signal isolation without external transformers.
• Provides high common-mode transient immunity to maintain signal integrity in noisy environments.
• Supports flexible power supply configurations with independent primary and secondary side supplies.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safety-certified signal barriers
• Power metering circuits for accurate energy measurement

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the D1 variant matches the required 3:1 channel directionality for your circuit design. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when four isolated channels are necessary for bidirectional or unidirectional data transfer. The 5000 Vrms rating suits applications demanding high isolation voltage. Consider the 150 Mb/s speed limit for high-frequency communication needs. Evaluate the 16-SOIC package size against available board space constraints.

Part Context

This part belongs to the ADuM241 series of robust digital isolators. It shares the same core isolation architecture as other variants in the family but differs in channel count and directionality. The series is designed for applications requiring reliable data transmission across isolation barriers in industrial and medical settings.

Replacement Considerations

ADUM241E1BRIZ serves as a qualified automotive-grade alternative within the same manufacturer lineup. Verify that the E1 variant meets any specific AEC-Q100 requirements if applicable to your production environment.
