ADUM2400ARWZ

Overview

The ADUM2400ARWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation voltage with a data rate of 1Mbps and common mode transient immunity of 25kV/µs. The device operates on a single supply voltage range of 2.7V to 5.5V, featuring unidirectional channels in a 16-SOIC package. Maximum propagation delay is 100ns, with typical rise/fall times of 3ns. It supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates four independent digital isolation channels within a compact surface-mount package
• Utilizes monolithic air core transformer technology for high-speed signal transmission
• Provides robust common mode transient immunity for reliable operation in noisy environments

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal interfaces demanding high safety isolation
• Power electronics gate drive circuits for inverters and converters

Procurement Notes

Verify the specific suffix ARWZ corresponds to the tube packaging format when ordering. Confirm that the 5000Vrms isolation rating meets the safety requirements of the target application. Ensure the 2.7V to 5.5V supply voltage range aligns with the system power design. Check RoHS compliance status for regulatory adherence in restricted substance zones.

Selection Notes

Select this component when four isolated channels are required in a single footprint. The 1Mbps data rate suits moderate speed applications compared to higher-speed variants. The 5000Vrms isolation level offers enhanced safety margins over lower-rated devices. Consider the 16-SOIC package dimensions for PCB layout constraints and thermal management needs.

Part Context

This part belongs to the ADuM240x series of quad-channel digital isolators from Analog Devices. It shares the iCoupler architecture with related models like ADUM2401 and ADUM2402. These devices replace traditional optocouplers by offering superior performance, smaller size, and better consistency across manufacturing batches.

Replacement Considerations

Direct substitutes include ADUM2401ARWZ and ADUM2402ARWZ. Verify channel configuration differences, as these variants may have different input/output pin assignments despite similar electrical specifications.
