ADUM241D0BRWZ-RL

Overview

The ADUM241D0BRWZ-RL is a robust quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four channels with a 3:1 input-to-output configuration (three forward, one reverse). The device supports data rates up to 150 Mb/s and offers an isolation voltage of 5000 Vrms. Key electrical parameters include a propagation delay of 7.2 ns and a supply current of 11.4 mA. It operates within a temperature range of -40°C to +125°C and is housed in a 16-pin SOIC package.

Feature Summary

• Robust iCoupler magnetic coupling technology for high reliability
• Quad channel isolation with 3:1 directional configuration
• High common-mode transient immunity for noisy environments
• Wide operating temperature range suitable for industrial applications

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal transmission across isolation barriers
• Power metering circuits for accurate energy measurement
• Inverters and motor drives for control signal isolation

Procurement Notes

Verify the specific suffix 'D0' against the official Analog Devices datasheet to confirm the exact insulation rating and channel directionality. Ensure the 'WZ' suffix corresponds to the correct RoHS-compliant lead-free packaging variant. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status, as supply constraints may apply to this specific reel configuration.

Selection Notes

Select this component when a quad-channel isolator with asymmetric 3:1 channel distribution is required. It is suitable for designs needing 5000 Vrms isolation with low power consumption. Consider the 16-SOIC package dimensions for PCB layout compatibility. Verify that the 150 Mbps data rate meets the system's communication speed requirements and that the unidirectional nature aligns with the signal flow topology.

Part Context

This part belongs to the ADuM241 family of robust digital isolators. It shares the same core architecture as other variants in the series but differs in insulation ratings and channel configurations. The family is designed for applications demanding high reliability and noise immunity in harsh electrical environments.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include ADUM241E1WBRWZ-RL and ADUM241E1BRIZ. Verify that the replacement matches the 3:1 channel configuration and 5000 Vrms isolation requirement before integration.
