ADUM131D0BRZ

Digital Isolators Overview

The ADUM131D0BRZ is a triple-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 16-SOIC package with three channels configured as two unidirectional forward and one reverse channel. Key electrical parameters include a data rate of 150 Mb/s, insulation voltage of 3000 Vrms, and common-mode transient immunity of 75 kV/µs. The device operates on supply voltages between 1.8 V and 5.5 V, drawing 8.8 mA typical current. Propagation delay is 7.2 ns, with rise/fall times of 2.5 ns. It supports SPI protocols and functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates three independent digital isolation channels using proprietary iCoupler magnetic coupling technology for signal transmission across isolation barriers.
• Provides high robustness against electromagnetic interference with a common-mode transient immunity rating of 75 kV/µs.
• Supports bidirectional communication through a configuration of two forward and one reverse channel within a single compact package.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation for sensor interfaces
• Medical equipment needing reliable signal isolation in patient monitoring devices
• Power electronics control circuits involving isolated gate driving or feedback loops

Digital Isolators Procurement Notes

Verify the specific suffix BRZ indicates tube packaging when ordering. Confirm the D0 variant corresponds to the 3000 Vrms insulation rating rather than higher ratings found in other series members. Ensure compatibility with 16-SOIC footprint requirements during PCB layout. Check RoHS compliance status directly with the manufacturer documentation prior to procurement.

Digital Isolators Selection Notes

Select this component when three isolated channels are required in a space-constrained design. The 150 Mb/s data rate suits moderate-speed digital communication needs. Consider the 3000 Vrms isolation level against system voltage requirements. The wide operating temperature range makes it suitable for harsh industrial environments compared to commercial-grade alternatives.

Digital Isolators Part Context

This part belongs to the ADUM131D family of general-purpose digital isolators. It shares architectural similarities with the ADUM131D1BRWZ but differs in insulation voltage ratings and packaging type. The family utilizes silicon dioxide layers and copper coils for isolation, offering advantages over optical isolators regarding size and power consumption.

Digital Isolators Replacement Considerations

The ADUM131D1BRZ serves as a related variant with potentially different insulation specifications. Verify channel count and isolation voltage ratings before substitution. The ADUM121N1BRZ offers only two channels and requires significant redesign if used as a replacement.
