ADUM1300BRW

Overview

The ADUM1300BRW is a triple-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 2500 Vrms isolation voltage with unidirectional signal transmission. The device supports data rates up to 10 Mb/s and operates within a supply voltage range of 2.7 V to 5.5 V. Key electrical parameters include a typical propagation delay of 32 ns and rise/fall times of 3 ns. It functions reliably across an operating temperature range of -40°C to +105°C. The component is housed in a 16-lead SOIC package.

Feature Summary

• Integrates three independent digital isolator channels using proprietary iCoupler magnetic coupling technology for robust signal transmission.
• Provides high common-mode transient immunity (CMTI) of 25 kV/µs to maintain signal integrity in noisy environments.
• Features low power consumption characteristics suitable for battery-operated applications while maintaining high-speed data transfer capabilities.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral devices.
• Medical equipment interfaces needing certified isolation barriers for patient safety compliance.
• Power electronics control circuits where high-voltage noise rejection is critical for stable operation.

Procurement Notes

Verify the specific suffix and packaging configuration against official Analog Devices documentation before procurement. Confirm that the 16-SOIC tube packaging matches your assembly requirements. Ensure compatibility with your system's voltage levels and isolation voltage ratings. Cross-reference the manufacturer part number to avoid confusion with similar series components like the ADUM130E1BRWZ which offers higher speed specifications.

Selection Notes

Select this component when a balance of moderate data rate and cost-effectiveness is required for triple-channel isolation. It is suitable for applications where 10 Mb/s throughput is sufficient and lower power consumption is prioritized over the higher speeds offered by the E-series variants. Ensure the 2500 Vrms isolation rating meets your safety standards compared to higher-rated alternatives.

Part Context

This device belongs to the ADUM1300 series of general-purpose digital isolators. It serves as a legacy or standard option within the iCoupler portfolio, offering reliable performance for basic isolation needs. It complements higher-speed variants like the ADUM130E series, providing a distinct trade-off between data rate and power efficiency for different design constraints.

Replacement Considerations

The ADUM1300BRW-RL is the reel-packaged equivalent of this tube-part. For higher speed requirements, consider the ADUM130E1BRWZ series. Verify pinout compatibility if substituting with other triple-channel isolators from different manufacturers.
