ADUM1286CRZ-RL7

Overview

The ADUM1286CRZ-RL7 is a dual-channel digital isolator manufactured by Analog Devices Inc., housed in an 8-pin SOIC package. It operates on a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides 3000 Vrms isolation via magnetic coupling technology, with a typical propagation delay of 24 ns and rise/fall times of 3 ns. It functions within a temperature range of -40°C to +125°C and draws 15 mA of operating current.

Feature Summary

• Provides galvanic isolation between circuits using magnetic coupling technology for signal transmission.
• Features bidirectional data flow capability with default low output configuration.
• Supports high common-mode transient immunity to maintain signal integrity in noisy environments.

Applications

• Industrial communication interfaces requiring robust noise rejection
• Medical equipment signal isolation
• Power management system monitoring

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-8 footprint matches the target PCB design constraints. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component for applications requiring dual-channel isolation with moderate speed requirements. The 100 Mb/s data rate suits standard industrial protocols. Consider the 3000 Vrms insulation rating for safety-critical barriers. Evaluate the 15 mA power consumption against system efficiency targets compared to lower-power alternatives.

Part Context

This part belongs to the ADUM1286 series of digital isolators from Analog Devices. It utilizes capacitive or magnetic isolation principles distinct from optical couplers. The series offers various channel configurations and insulation ratings tailored for interface isolation needs in demanding electronic environments.

Replacement Considerations

Check for ADUM1286 variants with different insulation ratings or package types. Verify pinout compatibility before substituting with other dual-channel isolators. Ensure equivalent CMTI and propagation delay specifications are met by potential replacements.
