ADUM131D0BRZ-RL7

Overview

The ADUM131D0BRZ-RL7 is a triple-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 3000 Vrms isolation with a data rate of 150 Mb/s and common-mode transient immunity of 75 kV/µs. The device operates on supply voltages from 1.8 V to 5 V, drawing 8.8 mA typical current. It features unidirectional signal paths with two forward and one reverse channel. Key timing parameters include a propagation delay of 7.2 ns and rise/fall times of 2.5 ns. It functions within a temperature range of -40°C to +125°C in a 16-pin SOIC package.

Feature Summary

• Implements iCoupler magnetic coupling for robust signal isolation without external transformers
• Provides high common-mode transient immunity to protect against noise spikes
• Supports SPI protocol communication for digital interface applications
• Operates across wide industrial temperature ranges with low power consumption

Applications

• Medical equipment needing reliable signal separation
• Power metering circuits for accurate data transmission
• Inverter gate drive interfaces for motor control

Procurement Notes

Verify the specific suffix D0 against the official Analog Devices datasheet to confirm channel directionality and pinout configuration. Ensure the SOIC-16 package width matches your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Selection Notes

Select this component when unidirectional isolation with moderate speed is required. Compare CMTI ratings against system noise environments to ensure reliability. Verify that the 150 Mb/s data rate meets the application's bandwidth needs. Check supply voltage compatibility with both logic sides of the isolated circuit.

Part Context

This part belongs to the ADuM131D series of triple-channel digital isolators. It shares the core iCoupler architecture with other variants in the family but differs in channel configuration and directionality. The series is designed for general-purpose isolation tasks where size and power efficiency are critical constraints.

Replacement Considerations

Check Analog Devices documentation for direct pin-compatible substitutes within the ADuM131x family. Verify if ADUM131D1BRZ-RL7 offers different channel directionality suitable for the design. Ensure any replacement maintains the same 3000 Vrms isolation rating and 150 Mb/s speed.
