ADUM5212CRSZ-RL7

Overview

The ADUM5212CRSZ-RL7 is a dual-channel digital isolator manufactured by Analog Devices Inc. It integrates an internal DC/DC converter to provide isolated power and signal transmission. The device operates with a maximum supply voltage of 5.5 V and supports data rates up to 100 Mb/s. It features magnetic coupling isolation with a rated insulation voltage of 2500 Vrms. The component is housed in a 20-lead SSOP package and is designed for unidirectional signal transfer.

Feature Summary

• Integrates an internal DC/DC converter to eliminate the need for external isolated power supplies
• Utilizes magnetic coupling technology for high-reliability signal isolation
• Supports high-speed data transmission at rates up to 100 Mb/s

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation barriers
• Power metering circuits with isolated communication interfaces

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm availability status as distribution channels may report limited stock or discontinuation. Ensure the SSOP-20 footprint matches the target PCB layout. Validate that the 2500 Vrms insulation rating meets the safety requirements of the end application environment.

Selection Notes

Select this component when bidirectional isolation is not required, as it supports only unidirectional channels. Consider the integrated power converter if board space for external magnetics is constrained. Compare against the ADUM6212 series if higher insulation voltage ratings are necessary for the specific system design constraints.

Part Context

This part belongs to the ADUM5212 family of digital isolators from Analog Devices. It is distinct from the ADUM347x series which offers bidirectional capabilities. The component falls under the Interface ICs subcategory within the broader digital isolator product line.

Replacement Considerations

The ADUM5212ARSZ-RL7 serves as a verified alternative within the same family, offering identical functionality with potentially different temperature or performance grades.
