ADUM6211BRSZ

Overview

The ADUM6211BRSZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology for magnetic coupling isolation. It integrates an isolated DC-to-DC converter to provide regulated power across the isolation barrier. The device supports bidirectional data transmission with a data rate of 25 Mbps and offers a common-mode transient immunity of 25 kV/µs. It operates within a supply voltage range of 3.135 V to 5.5 V and features a propagation delay of 35 ns. The component is housed in a 20-pin SSOP package and is rated for operation between -40°C and +105°C.

Feature Summary

• Integrates an isolated DC-to-DC converter providing adjustable regulated power output across the isolation barrier
• Employs iCoupler magnetic coupling technology for high-speed digital signal isolation without optical components
• Delivers high common-mode transient immunity to maintain signal integrity in noisy environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation barriers
• Power electronics control circuits with high-voltage noise rejection

Procurement Notes

Verify the specific suffix BRSZ corresponds to the SSOP-20 package and reel/tape configuration required for your assembly process. Confirm that the integrated DC-DC converter meets the voltage regulation needs of the isolated side. Ensure compatibility with the host system's logic levels and check for any RoHS compliance documentation updates prior to final procurement approval.

Selection Notes

Select this component when a compact solution is needed that combines data isolation with integrated power conversion. It is suitable for designs where space constraints prevent separate isolated power supplies. Consider the 25 Mbps data rate and 25 kV/µs CMTI for high-noise industrial applications. Verify that the 20-pin SSOP footprint fits the PCB layout requirements.

Part Context

This part belongs to the ADuM621x family of dual-channel isolators with integrated power converters. It replaces older solutions that required discrete isolated power supplies alongside standard digital isolators. The iCoupler technology allows for smaller form factors and higher reliability compared to traditional optocouplers in similar isolation applications.

Replacement Considerations

Direct replacements include other parts from the ADuM621x series with compatible pinouts and electrical characteristics. Verify that substitute devices support the same 3750 Vrms isolation rating and integrated DC-DC converter functionality. Check for package compatibility if switching between SSOP variants.
