ADUM2211SRIZ-RL

Overview

The ADuM2211SRIZ-RL is a dual-channel digital isolator utilizing Analog Devices iCoupler technology, which integrates high-speed CMOS logic and monolithic air-core transformer coils on a single silicon chip. It provides galvanic isolation with a rated insulation voltage of 5000 Vrms. The device supports unidirectional data transmission at a maximum data rate of 1 Mb/s. It operates within a supply voltage range of 3 V to 5.5 V and features typical propagation delays of 150 ns with rise and fall times of 10 ns. The component is housed in a 16-pin SOIC package and is designed for operation across an industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrates dual-channel isolation using proprietary iCoupler technology combining CMOS and air-core transformers
• Provides robust galvanic isolation with high common-mode transient immunity
• Supports unidirectional signal transmission with low power consumption characteristics

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high-voltage noise environments

Procurement Notes

Verify the specific suffix 'RL' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as regulatory requirements may vary by region and manufacturing date code. Ensure the supplier provides valid traceability documentation for the Analog Devices Inc. manufacturer part number. Check for any regional distribution restrictions or limited availability notices prior to finalizing procurement orders.

Selection Notes

Select this component when dual-channel unidirectional isolation is required with moderate data rates up to 1 Mbps. The 16-SOIC package facilitates surface-mount assembly in space-constrained designs. Consider the 5000 Vrms insulation rating for applications demanding significant potential differences between circuit domains. Evaluate the 3 V to 5.5 V operating range against system power supply constraints.

Part Context

This part belongs to the ADuM221x series of digital isolators from Analog Devices. These devices are engineered to replace traditional optocouplers, offering superior performance in speed, power efficiency, and reliability. The series leverages semiconductor process technology to create compact, integrated isolation solutions suitable for modern electronic designs.

Replacement Considerations

Direct replacements include other parts within the ADuM221x family, such as the ADuM2210, depending on channel configuration needs. Verify pinout compatibility and electrical specifications before substituting. Cross-reference with current industry-standard isolators if legacy support is required.
