ADUM5211CRSZ-RL7

Overview

The ADUM5211CRSZ-RL7 is a dual-channel digital isolator from Analog Devices, featuring integrated DC-to-DC converters for power delivery across the isolation barrier. It operates within a supply voltage range of 3.135 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides 2500 Vrms insulation strength and exhibits a typical propagation delay of 15 ns. It is housed in a 20-lead SSOP package and functions unidirectionally with a common-mode transient immunity of 25 kV/µs.

Feature Summary

• Integrates isolated DC-to-DC converters to eliminate external transformer requirements
• Provides magnetic coupling-based signal isolation for high noise immunity
• Supports high-speed data transmission at rates up to 100 Mb/s

Applications

• Isolated RS-232 transceivers
• Industrial process control systems
• Medical equipment requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'RL7' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the SSOP-20 footprint matches your PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when bidirectional communication is not required, as it is unidirectional. It is suitable for applications needing integrated power conversion without external magnetics. Compare against the ADUM5411 series if four channels are needed instead of two.

Part Context

This part belongs to the ADuM5211 family of dual-channel isolators with integrated power supplies. It utilizes Analog Devices' iCoupler technology for magnetic signal transmission. The device simplifies design by combining isolation and power management in a single package.

Replacement Considerations

The ADUM5211ARSZ is a tube-packaged variant of the same functional device. Verify pinout compatibility and thermal characteristics when substituting between reel and tube packages.
