ADUM161N1BRZ-RL7

Digital Isolators Overview

The ADUM161N1BRZ-RL7 is a robust six-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features unidirectional data flow with a maximum data rate of 150 Mb/s and an insulation voltage rating of 3000 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing a typical quiescent current of 17.3 mA. It exhibits a propagation delay of 7.2 ns and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a 16-pin SOIC format, it is supplied in reel, cut tape, or MouseReel configurations.

Digital Isolators Feature Summary

• Provides galvanic isolation via magnetic coupling technology for noise immunity
• Supports high-speed digital communication at rates up to 150 Mb/s
• Ensures safety compliance with a 3000 Vrms insulation voltage rating
• Delivers consistent performance across industrial temperature extremes

Digital Isolators Applications

• Industrial automation control systems requiring multi-channel isolation
• Medical equipment needing robust patient isolation barriers
• Power electronics interfaces for gate drive signal transmission
• Inverter and motor drive applications with high common-mode transients

Digital Isolators Procurement Notes

Verify the specific suffix RL7 to confirm reel packaging configuration. Ensure compatibility with SOIC-16 footprint requirements during PCB layout. Confirm that the unidirectional channel orientation matches the system signal flow design. Check for moisture sensitivity level handling procedures if storage conditions exceed specified limits prior to reflow soldering.

Digital Isolators Selection Notes

Select this component when six isolated channels are required for unidirectional signaling. Consider the 150 Mb/s data rate capability against system bandwidth needs. Evaluate the 17.3 mA power consumption against thermal management constraints. Verify that the 3000 Vrms isolation rating meets regulatory safety standards for the target application environment.

Digital Isolators Part Context

This part belongs to the ADUM161N series of robust digital isolators designed for demanding environments. It shares the SOIC-16 package and magnetic coupling architecture with other members like the ADUM163N. The N1 suffix indicates the specific pinout and channel configuration for six unidirectional isolators. It serves as a high-density alternative to discrete isolation solutions in complex interface designs.

Digital Isolators Replacement Considerations

Direct substitutes include ADUM161N1BRZ for tube packaging. For different channel counts, consider ADUM151N1BRZ-RL7 (five channels) or ADUM163N0BRZ-RL7 (six channels, bidirectional). Verify pinout compatibility before swapping between variants within the ADUM161N family.
