ADUM6212BRSZ-RL7

Overview

The ADUM6212BRSZ-RL7 is a dual-channel digital isolator from Analog Devices, housed in a 20-lead SSOP package. It features magnetic coupling isolation with an insulation voltage of 3750 Vrms and supports data rates up to 100 Mb/s. The device operates at a fixed supply voltage of 5.5 V with a propagation delay of 15 ns. It includes an integrated DC/DC converter for isolated power delivery. The component functions unidirectionally across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a high-frequency DC/DC converter to provide isolated power supply capability within the isolator circuit.
• Utilizes silicon dioxide (SiO2) isolation technology combined with magnetic coupling for signal transmission.
• Provides robust galvanic isolation between input and output domains without requiring external transformer components.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics monitoring circuits

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SSOP-20 footprint matches the design layout exactly. Check for any recent product change notices that might affect pinout or electrical characteristics before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel isolator with integrated isolated power is required. The 3750 Vrms insulation rating suits applications demanding high isolation strength. The 100 Mb/s data rate supports standard industrial protocols. Consider the 20-SSOP package size for board space constraints compared to wider SOIC options.

Part Context

This part belongs to the ADUM6212 series of digital isolators. It shares the core isolation architecture with other members but differs in channel count and power integration. The RL7 suffix denotes tape-and-reel packaging suitable for automated assembly processes.

Replacement Considerations

Direct substitutes include ADUM6212ARSZ variants with different packaging. Cross-reference ADUM6210 series for similar functionality without integrated power. Verify pin compatibility and thermal performance before swapping.
