ADUM6212BRSZ

Overview

The ADUM6212BRSZ is a dual-channel digital isolator from Analog Devices, featuring integrated DC-to-DC converters for power delivery across the isolation barrier. It utilizes magnetic coupling technology to provide electrical isolation with a rated insulation voltage of 3750 Vrms. The device supports unidirectional data transmission at a maximum data rate of 100 Mb/s per channel. It operates within a supply voltage range of 3.135 V to 5.5 V and functions reliably in temperatures from -40°C to +105°C. Packaged in an SSOP-20 format, it offers low propagation delay and high common-mode transient immunity.

Feature Summary

• Integrates on-chip DC-to-DC converters to eliminate external isolated power supplies
• Employs proprietary iCoupler magnetic coupling technology for signal transmission
• Provides robust galvanic isolation between input and output domains
• Supports high-speed digital communication with minimal signal distortion

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing patient isolation barriers
• Power electronics monitoring circuits
• Inverter gate drive isolation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm package integrity and pin alignment against the SSOP-20 specification before integration. Ensure compliance with RoHS directives as indicated in official documentation. Validate that the specific suffix matches the required tape-and-reel or tube packaging configuration for your assembly process.

Selection Notes

Select this component when dual-channel isolation with integrated power conversion is required. Compare performance metrics such as propagation delay and current consumption against alternative isolators. Consider the thermal management requirements associated with the internal DC/DC converter operation. Evaluate the footprint compatibility with existing PCB layouts designed for SSOP-20 packages.

Part Context

This part belongs to the ADuM62xx series of dual-channel isolators with integrated power stages. It complements other variants like the ADUM6210 and ADUM6211 by offering specific speed and isolation ratings. The series addresses applications demanding compact solutions for isolated power and data transfer without external magnetics.

Replacement Considerations

Check for direct equivalents within the ADUM62xx family, such as the ADUM6210CRSZ, noting differences in insulation voltage and data rate. Verify pinout compatibility before substituting with similar products from other manufacturers.
