ADUM1301BRW

Overview

The ADUM1301BRW is a triple-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 2500Vrms isolation voltage with a data rate of 10Mbps and 25kV/µs common-mode transient immunity. The device operates on a single supply voltage ranging from 2.7V to 5.5V. It features unidirectional channel configuration in a 16-SOIC package, supporting an operating temperature range of -40°C to +105°C.

Feature Summary

• Triple-channel digital isolation based on iCoupler magnetic coupling technology
• High common-mode transient immunity for noise-resistant signal transmission
• Unidirectional data flow capability across all three channels
• Wide operating voltage and temperature ranges for industrial reliability

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment signal interfaces needing safety isolation
• Power electronics gate drive circuits
• Inverter and motor control applications

Procurement Notes

Verify the specific suffix (e.g., BRWZ vs BRW) against the manufacturer's current datasheet to ensure package and tape-and-reel specifications match your assembly requirements. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when three isolated bidirectional or unidirectional channels are required within a compact footprint. Consider the 10Mbps data rate limit and 2500Vrms isolation rating against system requirements. Evaluate power consumption characteristics relative to other iCoupler variants if low-power operation is critical for the application design.

Part Context

This component belongs to the Analog Devices ADuM1300/ADuM1301 series of general-purpose digital isolators. It is part of the iCoupler family, which integrates transformer-based isolation technology directly into the CMOS process. This series offers an alternative to traditional optocouplers with improved performance consistency and smaller form factors.

Replacement Considerations

The ADUM1300BRW is a pin-compatible dual-channel variant within the same series. Verify channel count requirements before substitution. Other iCoupler devices may offer different isolation voltages or data rates but require schematic review for compatibility.
