ADUM2211SRWZ-RL

Overview

The ADUM2211SRWZ-RL is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates on a single 3 V to 5.5 V supply with typical quiescent currents of 1.1 mA and 1.3 mA per channel. The device provides 5000 Vrms isolation voltage and supports data rates up to 1 Mb/s. It features high common-mode transient immunity exceeding 25 kV/µs and propagation delays of approximately 150 ns. Packaged in a 16-pin SOIC (Wide) surface-mount format, it functions within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Integrates two independent bidirectional channels using iCoupler magnetic coupling for galvanic isolation.
• Provides robust signal integrity with high common-mode transient immunity exceeding 25 kV/µs.
• Supports flexible logic levels through integrated level translation capabilities between 3.3 V and 5 V domains.
• Delivers low power consumption suitable for battery-operated or energy-efficient system designs.

Applications

• General-purpose multichannel isolation in industrial automation systems
• Isolation interfaces for medical equipment requiring safety compliance
• Power supply control circuits and gate driver isolation
• RS-232, RS-422, and RS-485 communication line isolation

Procurement Notes

Verify the specific suffix 'SRWZ-RL' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the 16-SOIC wide package. Confirm that the required isolation voltage rating meets your system's safety standards before finalizing procurement.

Selection Notes

Select this component when dual-channel isolation is required with moderate data rates up to 1 Mbps. It is appropriate for applications needing high common-mode noise rejection and low power dissipation. Consider alternative models if higher data speeds or different channel counts are necessary. Verify thermal performance requirements for the intended operating environment.

Part Context

This part belongs to the ADuM family of iCoupler digital isolators, which integrate transformer and CMOS technology on a single monolithic chip. The series offers various configurations for single, dual, quad, and octal channel isolation needs. These devices replace traditional optocouplers by providing superior performance in speed, power, and reliability without requiring external components.

Replacement Considerations

Direct substitutes include other ADUM2211 variants with different packaging or reel options, such as ADUM2211SRWZ. Cross-family replacements may require evaluation of pinout compatibility and isolation voltage ratings. Always verify electrical parameters against the original design requirements when substituting.
