ADUM1286WCRZ-RL7

Overview

The ADUM1286WCRZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides an insulation voltage of 3000 Vrms and features bidirectional channel polarity. Key electrical parameters include a typical propagation delay of 24 ns, rise and fall times of 3 ns, and a pulse width distortion of 10 ns. It functions reliably across an operating temperature range of -40°C to +125°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Employs proprietary magnetic coupling technology to provide robust galvanic isolation between circuits without optical components.
• Supports bidirectional data transmission on both channels, allowing flexible signal routing in complex systems.
• Delivers high-speed performance with a maximum data rate of 100 Mb/s and low propagation delay for precise timing.
• Ensures safety compliance with a reinforced insulation rating of 3000 Vrms for harsh electrical environments.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation and safety compliance
• Power electronics control circuits with high-voltage noise immunity
• Automotive electronic modules meeting AEC-Q100 standards

Procurement Notes

Verify the specific suffix WCRZ-RL7 against official Analog Devices documentation to confirm the reel packaging configuration and temperature grade. Ensure compatibility with existing PCB footprints for the SOIC-8 package. Cross-reference the datasheet for any recent process change notices or lifecycle status updates before finalizing procurement plans.

Selection Notes

Select this component when bidirectional isolation is required at speeds up to 100 Mb/s. Compare power consumption metrics against unidirectional alternatives if lower current draw is critical. Confirm that the 3000 Vrms insulation level meets the specific safety regulations of the target application environment.

Part Context

This part belongs to the ADUM1286 series of dual-channel digital isolators. It shares the SOIC-8 footprint with other variants but differs in channel directionality and speed specifications. The series is designed to replace traditional optocouplers in space-constrained designs while offering superior performance and reliability.

Replacement Considerations

Check for ADUM1286BRZ-RL7 for unidirectional applications or ADUM1285WCRZ-RL7 for different speed/power profiles. Verify pinout compatibility and insulation ratings before substituting.
