ADUM6211CRSZ-RL7

Overview

The ADUM6211CRSZ-RL7 is a dual-channel digital isolator from Analog Devices, housed in a 20-pin SSOP package. It features integrated DC/DC converters for isolated power delivery. Key electrical parameters include a data rate of 100 Mb/s, an insulation voltage of 3750 Vrms, and unidirectional signal transmission. The device operates within a supply voltage range of 3 V to 5.5 V, with a typical propagation delay of 15 ns. It supports a wide operating temperature range from -40°C to +105°C and utilizes magnetic coupling technology for isolation.

Feature Summary

• Integrates on-chip DC/DC converters to provide isolated power supplies for the secondary side, eliminating the need for external isolated power sources.
• Employs proprietary cMOS technology with magnetic coupling to achieve high-speed digital signal isolation without optical components.
• Provides robust galvanic isolation between input and output circuits to protect sensitive electronics from high voltage transients.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power monitoring and control circuits in energy infrastructure

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance documentation matches current regulatory requirements. Check for specific lot traceability if required by quality management standards. Ensure storage conditions adhere to moisture sensitivity level specifications prior to assembly.

Selection Notes

Select this component when high-speed bidirectional data transfer is not required, as it supports only unidirectional channels. The integrated power converter simplifies board layout but requires attention to transformer placement. Compare against standard isolators if external isolated power is already available, as this part adds complexity for power generation.

Part Context

This part belongs to the ADUM6211 series of digital isolators designed for applications demanding both signal isolation and isolated power delivery. It complements other ADUM products that offer varying channel counts and data rates, providing a solution for systems where space constraints and power efficiency are critical design factors.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternative ADUM series devices based on channel count and power integration needs.
