ADUM3200CRZ-RL7

Overview

The ADUM3200CRZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. The device provides an isolation voltage of 2500 Vrms with a common-mode transient immunity (CMTI) of 25 kV/µs. Key electrical parameters include a typical propagation delay of 45 ns and rise/fall times of 2.5 ns. It functions in unidirectional mode across an operating temperature range of -40°C to +105°C.

Feature Summary

• Dual-channel architecture for independent signal isolation
• iCoupler magnetic coupling technology for high reliability
• Enhanced system-level ESD protection capabilities
• High common-mode transient immunity for noisy environments

Applications

• Industrial process control systems
• Medical equipment signal isolation
• Power management circuit interfaces
• General-purpose digital isolation in instrumentation

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Cross-reference the part number with the latest datasheet revision to confirm pinout and electrical specifications remain unchanged.

Selection Notes

Select this component for applications requiring bidirectional data flow separation using unidirectional channels. Compare against single-channel alternatives if only one isolated path is needed. Consider the 25 Mb/s speed limit against higher-speed isolators if data throughput exceeds requirements. Evaluate power consumption differences between 3 V and 5.5 V operation modes for battery-sensitive designs.

Part Context

This part belongs to the ADUM3200 series of dual-channel digital isolators. It shares the same core functionality as the ADUM3200BRZ but differs in packaging configuration. The series is designed to replace traditional optocouplers in modern electronic designs, offering superior performance in terms of speed, size, and reliability while maintaining galvanic isolation barriers.

Replacement Considerations

The ADUM1200BRZ is listed as a parameter-equivalent substitute by distributors.
