ADUM5212ARSZ-RL7

Overview

The ADUM5212ARSZ-RL7 is a dual-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It provides magnetic coupling isolation with a rating of 2500 Vrms and supports data rates up to 100 Mb/s. The device operates within a supply voltage range of 3.135 V to 5.5 V, drawing 1.1 mA or 2.7 mA depending on the channel configuration. It exhibits a propagation delay of 15 ns and functions reliably between -40°C and +105°C. Packaged in a 20-lead SSOP, it delivers up to 150 mW output power from the internal converter.

Feature Summary

• Integrates an isolated DC-to-DC converter for simplified power delivery across isolation barriers
• Provides high-speed signal transmission via magnetic coupling technology
• Offers robust insulation capabilities suitable for demanding industrial environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications with high voltage requirements

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the 20-lead SSOP package matches your PCB footprint. Ensure the operating temperature range meets your environmental specifications. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the integrated converter output aligns with your downstream circuit voltage needs.

Selection Notes

Choose this component when both signal isolation and isolated power generation are required in a single package. It is suitable for designs needing bidirectional or unidirectional data transfer with integrated power management. Consider the 15 ns propagation delay for timing-sensitive applications. Evaluate the 2500 Vrms isolation rating against your system's safety requirements. Assess the 150 mW power budget to ensure it supports your load.

Part Context

This part belongs to the ADuM5212 series of dual-channel digital isolators. It combines standard digital isolation with an integrated power converter. The series is designed for applications requiring high reliability and compact solutions. Analog Devices manufactures these components using CMOS technology for low power consumption.

Replacement Considerations

Check for direct pin-compatible substitutes within the ADuM family. Verify that alternative parts support similar isolation voltages and data rates. Ensure any replacement includes an integrated converter if power isolation is critical. Compare thermal performance and package dimensions for mechanical fit.
