ADUM2211WTRWZ

Digital Isolators Overview

The ADUM2211WTRWZ is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features bidirectional data channels with a maximum data rate of 10 Mb/s and an insulation voltage rating of 5000 Vrms. The device operates within a supply voltage range of 3 V to 5.5 V, drawing a typical operating current of 800 uA. It exhibits a propagation delay of 150 ns and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a SOIC-16 surface-mount format, it meets AEC-Q100 automotive qualification standards.

Digital Isolators Feature Summary

• Bidirectional signal transmission capability for two independent channels
• Robust 5000 Vrms insulation voltage rating for high-voltage isolation
• Low power consumption with 800 uA typical operating current
• Automotive-grade reliability certified under AEC-Q100 standards

Digital Isolators Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interfaces such as CAN and LIN buses
• Medical equipment needing reinforced safety isolation
• Power conversion systems with isolated gate drive circuits

Digital Isolators Procurement Notes

Verify the specific suffix WTRWZ indicates tape-and-reel packaging when sourcing. Confirm AEC-Q100 compliance requirements against project specifications. Check for moisture sensitivity labeling due to humidity-sensitive classification. Ensure the SOIC-16 footprint matches the target PCB design constraints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component for applications requiring bidirectional data flow over isolated barriers. Compare performance metrics against unidirectional variants like the ADUM2210 if directionality is not required. Evaluate power budgets considering the 800 uA quiescent current draw. Ensure the 10 Mb/s data rate suffices for the intended communication protocol speed requirements.

Digital Isolators Part Context

This part belongs to the ADUM2211 series of dual-channel digital isolators. It shares the core magnetic coupling architecture with other members of the family but differs in channel polarity and packaging options. The WTRWZ designation specifically denotes the reel-based packaging variant suitable for automated assembly processes.

Digital Isolators Replacement Considerations

The ADUM2211SRWZ-RL serves as a tube-packaged alternative within the same electrical specification set. Verify pinout compatibility and thermal characteristics when substituting between reel and tube formats.
