ADUM6211ARSZ

Overview

The ADUM6211ARSZ is a dual-channel digital isolator from Analog Devices, featuring integrated isoPower isolated DC-to-DC converters. It operates within a supply voltage range of 3.15 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides 3750 Vrms insulation strength via magnetic coupling technology. Key electrical parameters include a propagation delay of 15 ns, a common-mode transient immunity of 25 kV/µs, and a maximum power dissipation of 2.5 W. It functions in unidirectional mode and is housed in a 20-pin SSOP package.

Feature Summary

• Integrates isolated DC-to-DC converter for regulated power delivery
• Utilizes iCoupler magnetic coupling technology for signal isolation
• Provides high common-mode transient immunity for noise rejection

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power electronics gate drive circuits

Procurement Notes

Verify the specific suffix 'ARSZ' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Confirm that the required insulation voltage rating of 3750 Vrms meets the safety standards of the target application. Check for any recent lifecycle status updates or alternative package options if availability is constrained.

Selection Notes

Select this component when dual-channel isolation with integrated power conversion is required. Ensure the system design accommodates the 3.15 V to 5.5 V operating voltage range. Verify that the 100 Mb/s data rate suffices for the communication needs. Consider the thermal management requirements given the 2.5 W power dissipation capability in the SSOP-20 package.

Part Context

This part belongs to the ADuM621x series of dual-channel digital isolators. It shares architectural similarities with the ADUM6210 and ADUM6212 models but differs in insulation voltage ratings and channel directionality configurations. The series leverages Analog Devices' proprietary iCoupler technology to replace traditional optocouplers in space-constrained designs.

Replacement Considerations

The ADUM6210CRSZ-RL7 offers similar functionality but with different insulation characteristics. Verify pin compatibility before substitution. No direct public substitute part numbers are confirmed for identical specifications.
