ADUM1100BRZ-RL7

Overview

The ADUM1100BRZ-RL7 is a single-channel digital isolator utilizing iCoupler technology, which integrates high-speed CMOS circuitry with monolithic air-core transformer coupling. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. Key electrical specifications include an insulation voltage of 2500 Vrms, a typical propagation delay of 18 ns, and a common-mode transient immunity of 25 kV/µs. The device functions reliably across an extended temperature range from -40°C to +125°C, drawing a typical operating supply current of 800 µA.

Feature Summary

• Integrates high-speed CMOS logic with monolithic air-core transformer technology for signal isolation.
• Provides unidirectional data transmission capability for single-channel applications.
• Ensures robust isolation performance with high insulation voltage ratings.

Applications

• General-purpose digital isolation in industrial communication interfaces
• Isolation barriers in sensor systems requiring high common-mode transient immunity
• Power management circuits needing galvanic separation between control and power stages

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the BRZ variant meets the required thermal and electrical specifications for your application environment. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity. Check for any recent lifecycle status updates or obsolescence notices directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when a single-channel, unidirectional isolator is required with high speed and low power consumption. The 100 Mb/s data rate suits most standard digital protocols. Ensure the system voltage aligns with the 3 V to 5.5 V input range. Consider the SOIC-8 package constraints for PCB layout and verify that the 2500 Vrms isolation rating satisfies safety standards for the intended application.

Part Context

This part belongs to the ADuM1100 series of digital isolators from Analog Devices. The series leverages iCoupler technology to replace traditional magnetic or optical isolation components. The BRZ designation typically refers to the commercial temperature grade and lead-free RoHS-compliant packaging. The RL7 suffix denotes the tape and reel shipping format used for automated assembly processes.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM1100 family, such as the ARZ variant, if different temperature grades are needed. Verify that any substitute maintains the same 100 Mb/s data rate and 2500 Vrms isolation rating. Ensure the replacement part supports the required unidirectional configuration and SOIC-8 footprint.
