ADUM1300BRWZ

Overview

The ADUM1300BRWZ is a triple-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It provides 2500Vrms isolation voltage and supports data rates up to 10Mbps with a common mode transient immunity of 25kV/µs. The device operates on a single supply voltage ranging from 2.7V to 5.5V and features unidirectional channel configuration with three inputs on Side 1 and zero on Side 2. It is housed in a 16-SOIC package with a width of 7.50mm, designed for surface mount installation across an operating temperature range of -40°C to +105°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for robust signal transmission without external magnetics
• Provides high common mode transient immunity of 25kV/µs for noise-resistant operation
• Supports bidirectional communication capabilities within the isolator architecture
• Enables direct 3V/5V level translation between isolated domains

Applications

• Industrial automation systems requiring galvanic isolation
• Motor control circuits for feedback signal isolation
• Medical equipment needing reinforced isolation barriers
• Power electronics interfaces for gate drive isolation

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for specific packaging variants such as tube or reel options. Ensure the ordering suffix matches the required quantity format. Validate that the part number corresponds to the BRWZ variant specifications before finalizing purchase orders to avoid compatibility issues.

Selection Notes

Select this component when three independent unidirectional isolation channels are required within a compact SOIC footprint. Consider the 10Mbps data rate limit and 2500Vrms isolation rating against system requirements. Evaluate power consumption characteristics relative to the 2.7V to 5.5V supply range. Compare propagation delay specifications if timing precision is critical for the application interface.

Part Context

This device belongs to the ADUM1300 series of triple-channel digital isolators. It shares architectural similarities with other iCoupler products but is distinct in its specific channel count and speed ratings. The BRWZ suffix indicates a specific tape and reel or tube packaging option depending on distribution, while maintaining identical electrical performance characteristics to other variants in the base ADUM1300 family.

Replacement Considerations

Public confirmed substitute part numbers include ADUM1300ARW and ADUM1300WTRWZ. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any changes in packaging dimensions or thermal characteristics that might impact existing PCB layouts.
