ADUM5212BRSZ-RL7

Overview

The ADUM5212BRSZ-RL7 is a dual-channel digital isolator from Analog Devices, featuring an integrated DC/DC converter for isolated power delivery. It operates with unidirectional signal transmission at data rates up to 100 Mb/s and supports a maximum supply voltage of 5.5 V. The device provides 2500 Vrms isolation via magnetic coupling and exhibits a propagation delay of 15 ns. It functions within a temperature range of -40°C to +105°C and is housed in a 20-pin SSOP package.

Feature Summary

• Integrates an on-chip DC/DC converter to provide isolated power, eliminating the need for external isolated supplies.
• Utilizes magnetic coupling technology to achieve high-voltage electrical isolation between input and output channels.
• Supports high-speed digital communication with data rates reaching 100 Mb/s per channel.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm that the BRSZ variant matches the required thermal and mechanical specifications for your PCB layout. Ensure compatibility with the 20-SSOP footprint during procurement planning.

Selection Notes

Select this component when both signal isolation and isolated power generation are required in a single package. It is suitable for applications demanding high common-mode transient immunity and low propagation delay. Consider the SSOP-20 package constraints and thermal dissipation requirements during design.

Part Context

This part belongs to the ADUM5212 series of dual-channel digital isolators. It combines signal isolation with power conversion capabilities, distinguishing it from standard isolators that require separate isolated power sources. The RSZ suffix denotes the RoHS-compliant SSOP package type.

Replacement Considerations

Check for pin-compatible alternatives within the ADUM family that offer similar isolation ratings or different data rate requirements. Verify if other variants support the same integrated power topology without redesigning the power stage.
