ADUM2400BRIZ

Overview

The ADUM2400BRIZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports bidirectional communication at data rates up to 90 Mb/s. The device features an insulation voltage of 5000 Vrms and maintains signal integrity with propagation delays of 50 ns and rise/fall times of 3 ns. Designed for robust performance, it functions across an extended temperature range from -40°C to +105°C. Packaged in a 16-pin SOIC, it integrates high-speed CMOS circuitry with monolithic air core transformers.

Feature Summary

• Bidirectional communication capability with 3 V/5 V level translation
• High-temperature operation suitable for demanding environments
• Magnetic coupling isolation technology for signal transmission

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety barriers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check current availability as supply may be restricted. Ensure storage conditions align with manufacturer guidelines to maintain device integrity prior to assembly.

Selection Notes

Select this component when four independent isolated channels are required within a single package. Consider the 5000 Vrms insulation rating for safety-critical applications. Evaluate the 90 Mb/s data rate against system bandwidth needs. Verify that the SOIC-16 footprint fits the PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the ADuM240x series of digital isolators. It represents a solution combining high-speed CMOS logic with proprietary iCoupler technology. The series is designed to replace traditional optocouplers in applications demanding higher speed, lower power consumption, and improved reliability over long operational lifetimes.

Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully. Ensure any replacement maintains the required insulation voltage and channel count.
