ADUM130D1BRZ

Overview

The ADUM130D1BRZ is a triple-channel digital isolator utilizing Analog Devices iCoupler magnetic coupling technology. It provides robust signal isolation with a 3000 Vrms insulation voltage and a common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mb/s with a maximum propagation delay of 13 ns. It operates on a supply voltage range of 1.7 V to 5.5 V, drawing a typical operating current of 9.4 mA. Packaged in a 16-lead SOIC, it functions within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Triple-channel unidirectional signal isolation using iCoupler magnetic coupling technology
• High common-mode transient immunity rated at 75 kV/µs for noise rejection
• Wide operating supply voltage range supporting 1.7 V to 5.5 V logic levels
• Industrial temperature rating extending from -40°C to +125°C

Applications

• General-purpose digital isolation in mixed-signal systems
• Isolation for SPI communication interfaces
• Motor control circuitry requiring robust signal transfer
• Industrial automation sensor interface isolation

Procurement Notes

Verify the specific suffix 'D1' against the official Analog Devices datasheet to confirm pinout and functional configuration. Ensure the package matches the 16-SOIC specification and check for moisture sensitivity level requirements during storage and handling. Confirm that the 3000 Vrms isolation rating meets system safety standards before integration.

Selection Notes

Select this component when three isolated channels are required for unidirectional data transmission. It is suitable for applications needing high common-mode noise immunity and wide supply voltage flexibility. Consider the 13 ns propagation delay and 150 Mb/s speed limit relative to system timing requirements. Evaluate the 16-SOIC footprint constraints against available PCB space.

Part Context

This part belongs to the ADuM130 series of triple-channel digital isolators. It shares the core iCoupler architecture with variants like the ADUM130E1BRZ, differing primarily in electrical specifications such as propagation delay and pulse width distortion. The series is designed for general-purpose isolation tasks where size and power consumption are critical factors.

Replacement Considerations

The ADUM130E1BRZ is a documented substitute within the same family, offering similar functionality but with potentially different propagation delay characteristics. Verify that the replacement variant's electrical parameters align with the original design requirements before substitution.
