ADUM1210BRZ-RL7

Overview

The ADUM1210BRZ-RL7 is a dual-channel digital isolator utilizing iCoupler technology, which integrates high-speed CMOS circuitry with monolithic transformer isolation. It provides bidirectional data transmission across an electrical isolation barrier with a rated insulation voltage of 2500 Vrms. The device supports a data rate of 10 Mb/s and operates within a supply voltage range of 2.7 V to 5.5 V. Key electrical characteristics include a typical propagation delay of 50 ns and a low power consumption of 600 µA per channel. It functions reliably in industrial temperature ranges from -40°C to +105°C.

Feature Summary

• Integrates monolithic transformers for galvanic isolation without external magnetics
• Provides robust common-mode transient immunity for noisy environments
• Supports unidirectional signal transmission between isolated domains

Applications

• Industrial process control systems requiring signal isolation
• Medical equipment needing patient isolation barriers
• Power metering applications for accurate measurement separation

Procurement Notes

Verify the specific suffix RL7 indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer designation matches Analog Devices Inc. to ensure authenticity. Check current availability status as distribution may be limited or subject to allocation. Ensure compliance with RoHS directives if required by your manufacturing standards.

Selection Notes

Select this component when dual-channel isolation is required at moderate data rates. Compare against higher-speed variants like the ADUM121N series if throughput exceeds 10 Mb/s. Consider the SOIC-8 package constraints for PCB layout. Evaluate power budget requirements against the 600 µA per channel consumption profile.

Part Context

This part belongs to the ADuM121x family of digital isolators from Analog Devices. These devices replace traditional optocouplers by offering superior performance in speed, size, and reliability. The family utilizes proprietary silicon-on-insulator technology to create compact isolation barriers suitable for modern electronic designs.

Replacement Considerations

Direct functional equivalents include the ADUM1210BRZ (tube packaging) and the ADUM1210ARZ. For higher speed requirements, consider the ADUM121N series. Verify pin compatibility and isolation voltage ratings before substituting.
