ADUM2400CRWZ

Overview

The ADUM2400CRWZ is a quad-channel digital isolator utilizing iCoupler technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 120 Mb/s. The device provides 5000 Vrms isolation voltage and exhibits a common-mode transient immunity of 25 kV/µs. Key timing parameters include a propagation delay of 27 ns, with rise and fall times of 3 ns. It functions in unidirectional mode across four channels. Operating temperatures span from -40°C to +105°C. Power consumption varies by channel configuration, with typical currents listed as 18 mA and 70 mA.

Feature Summary

• Quad-channel architecture for multi-line signal isolation
• High common-mode transient immunity for noise rejection
• iCoupler magnetic coupling technology for robust isolation
• Wide operating temperature range for industrial environments

Applications

• Industrial process control systems
• Medical equipment requiring galvanic isolation

Procurement Notes

Verify the specific suffix (e.g., RL) against official Analog Devices documentation to confirm reel packaging specifications. Confirm current availability status directly with authorized distributors, as supply constraints may apply. Ensure the SOIC-16 package width matches your PCB layout requirements before finalizing orders.

Selection Notes

Select this component when high-density quad-channel isolation is required within a single package. The 5000 Vrms rating suits applications demanding significant potential differences between circuits. Consider the 120 Mb/s data rate capability for high-speed digital communication needs. Verify that the 2.7 V to 5.5 V supply range aligns with the target system's power rails.

Part Context

This part belongs to the ADuM2400 series of digital isolators from Analog Devices. These devices replace traditional optocouplers by offering superior performance in speed, size, and reliability. The series leverages silicon dioxide insulation layers to provide electrical isolation without optical components, enabling faster switching speeds and lower power consumption compared to legacy technologies.

Replacement Considerations

Check Analog Devices datasheets for direct pin-compatible alternatives within the ADuM2400 family, such as the ADUM2401 or ADUM2402, which may offer different channel configurations or polarity options while maintaining similar isolation characteristics.
