ADUM240D0BRIZ-RL

Overview

The ADUM240D0BRIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mb/s and an insulation voltage of 5000 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, consuming 9.4 mA of working power current. It exhibits a propagation delay of 7.2 ns and supports an operating temperature range from -40°C to +125°C. Packaged in a 16-pin SOIC, it provides robust signal isolation for industrial applications.

Feature Summary

• Provides four isolated unidirectional digital communication channels
• Utilizes iCoupler magnetic coupling technology for galvanic isolation
• Offers high common-mode transient immunity for noise rejection
• Supports wide operating temperature ranges for harsh environments

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and energy monitoring
• Inverter and motor drive interfaces

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when ordering. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the SOIC-16 package width matches your PCB footprint requirements. Cross-reference the manufacturer part number with official datasheets to confirm pinout compatibility before integration into existing designs.

Selection Notes

Select this component when four independent unidirectional isolation paths are required. The 150 Mb/s data rate suits moderate-speed digital signals. Consider the 5000 Vrms isolation rating for safety-critical barriers. Evaluate power consumption against system thermal constraints given the 9.4 mA typical current draw. Ensure the 2.7 V minimum supply voltage aligns with the target logic levels.

Part Context

This part belongs to the ADuM240 series of quad-channel digital isolators. It shares the SOIC-16 package form factor with other members like the ADUM2400 but differs in channel directionality and data rates. The series leverages Analog Devices' proprietary iCoupler technology to replace traditional optocouplers in space-constrained designs requiring high reliability.

Replacement Considerations

Direct substitutes include ADUM240D0BRIZ (non-reel) or ADUM240E variants if extended testing is needed. Check ADUM2400BRIZ-RL for bidirectional alternatives. Verify pin-to-pin compatibility and electrical parameter overlaps before swapping components in established hardware designs.
