ADUM1285BRZ-RL7

Overview

The ADUM1285BRZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 3000 Vrms isolation voltage with unidirectional signal transmission at data rates up to 25 Mb/s. The device operates within a supply voltage range of 3.135 V to 5.5 V and features default low output logic. Typical propagation delay is 23 ns, with rise and fall times of 3 ns. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Integrates dual-channel magnetic coupling for galvanic isolation without external transformers
• Provides robust 3000 Vrms insulation rating for high-voltage noise immunity
• Supports unidirectional data transmission with default low output configuration

Applications

• Industrial automation control systems requiring isolated communication
• Medical equipment needing patient isolation barriers
• Power electronics gate drive circuits for motor control

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Check current availability as distribution may be limited or subject to factory order constraints. Ensure the SOIC-8 footprint matches your PCB design requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring dual-channel isolation with moderate data speeds. Consider the 25 Mb/s limit against higher-speed alternatives if throughput demands exceed specifications. Evaluate the 3000 Vrms rating against system isolation requirements. Verify power consumption levels fit within thermal budgets for dense layouts.

Part Context

This part belongs to the ADUM1285 series of digital isolators. It shares the iCoupler architecture with other members but differs in channel count and speed. The BRZ designation typically indicates lead-free and halogen-free construction. The RL7 suffix specifies the tape and reel packaging format for automated assembly processes.
