ADUM241D0BRIZ-RL

Overview

The ADUM241D0BRIZ-RL is a general-purpose digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features four channels with a 3:1 input-to-output configuration in a 16-SOIC package. Key electrical parameters include a data rate of 150 Mb/s, isolation voltage of 5000 Vrms, and common-mode transient immunity of 75 kV/µs. The device operates within a temperature range of -40°C to +125°C and draws 11.4 mA of supply current.

Feature Summary

• Provides robust signal isolation via magnetic coupling technology
• Supports high-speed data transmission at 150 Mb/s
• Offers high common-mode transient immunity for noise rejection
• Configured with three forward and one reverse channel

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications with high-voltage interfaces
• Inverter control circuits in motor drives

Procurement Notes

Verify the specific suffix 'D0' against project requirements to ensure correct channel directionality and logic levels. Confirm that the SOIC-16 package dimensions match the PCB footprint. Check for RoHS compliance status if environmental regulations apply. Ensure the operating temperature range meets the system's thermal constraints. Validate supply chain availability as distribution may be limited.

Selection Notes

Select this component when a unidirectional isolator with asymmetric channel count is required. The 3:1 configuration suits applications where multiple signals flow one way and one returns. Consider the 150 Mb/s speed limit for bandwidth needs. Evaluate the 5000 Vrms isolation rating against system voltage stresses. Compare power consumption against other iCoupler variants if efficiency is critical.

Part Context

This part belongs to the ADuM241 series of robust digital isolators. It shares the core iCoupler architecture with similar models like the ADUM241E1BRIZ but differs in qualification and channel configuration. The series is designed for general-purpose isolation in harsh environments, offering reliability without external magnetics.

Replacement Considerations

The ADUM241D1BRWZ is listed as a parameter-equivalent substitute. Verify compatibility regarding package width and pinout before substitution.
