ADUM6211ARSZ-RL7

Overview

The ADUM6211ARSZ-RL7 is a dual-channel digital isolator from Analog Devices, featuring integrated isoPower isolated DC/DC conversion. It operates with unidirectional data channels at a maximum data rate of 100 Mb/s and provides an insulation voltage of 3750 Vrms via magnetic coupling. The device supports a supply voltage range of 5.5 V, exhibits a propagation delay of 15 ns, and functions within a temperature range of -40°C to +105°C. Packaged in a 20-lead SSOP for surface mount applications.

Feature Summary

• Integrates isolated DC/DC converter for simplified power delivery across isolation barrier
• Provides high-speed bidirectional data isolation with low propagation delay
• Utilizes iCoupler magnetic coupling technology for robust signal transmission

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Test and measurement instrumentation interfaces
• Power electronics control circuitry

Procurement Notes

Verify the specific suffix RL7 against official Analog Devices documentation to confirm reel packaging specifications and quantity. Ensure compatibility with existing board layouts regarding the SSOP-20 footprint. Cross-reference the datasheet revision history for any updates to electrical characteristics or recommended operating conditions prior to final procurement validation.

Selection Notes

Select this component when both data isolation and isolated power generation are required in a single package. Compare channel count and data rates against alternatives like the ADUM6212 if bidirectional communication is needed. Verify that the 3750 Vrms insulation rating meets the specific safety standards of the target application environment.

Part Context
