ADUM1201BRZ-RL7

Overview

The ADUM1201BRZ-RL7 is a dual-channel digital isolator utilizing Analog Devices' iCoupler technology. It features two channels with unidirectional data flow, supporting a data rate of 25 Mb/s and an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing a typical operating current of 6.3 mA. Key electrical parameters include a propagation delay of 50 ns, rise/fall times of 3 ns, and a common-mode transient immunity (CMTI) of 25 kV/µs. It functions reliably across an extended temperature range from -40°C to +105°C and is housed in an 8-pin SOIC package.

Feature Summary

• Implements magnetic coupling isolation via proprietary iCoupler technology for high-speed signal transmission
• Provides robust galvanic isolation with 2500 Vrms insulation rating and 25 kV/µs common-mode transient immunity
• Supports bidirectional power delivery through isolated DC-to-DC converters when paired with appropriate transformer circuits

Applications

• Industrial process control systems requiring isolated communication interfaces
• Medical equipment needing safety-certified signal isolation
• Power metering applications involving isolated energy measurement

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging configuration during procurement. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to integration. Ensure the ordering part number matches the required thermal grade and package variant exactly to avoid compatibility issues in final assembly.

Selection Notes

Select this component when dual-channel unidirectional isolation is required at speeds up to 25 Mb/s. Consider the 8-SOIC package constraints for PCB layout. Evaluate the 2.7 V to 5.5 V supply range against system power rails. Verify that the 2500 Vrms isolation rating meets the specific safety standards applicable to the target application environment.

Part Context

This part belongs to the ADuM120x series of dual-channel digital isolators. It shares the core iCoupler architecture with variants offering different channel directions or speed grades. The BRZ suffix typically denotes a specific temperature grade and lead-free packaging compliant with environmental directives within the broader Analog Devices isolation product family.

Replacement Considerations

Direct substitutes may include other ADuM120x variants such as ADUM1201ARZ or ADUM1201BRZ depending on temperature grade requirements. Cross-referencing pinouts and electrical specifications is essential when considering non-Analog Devices alternatives.
