ADUM5212CRSZ

Overview

The ADUM5212CRSZ 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 rated insulation voltage of 2500 Vrms. The device supports data rates up to 100 Mb/s and operates within a supply voltage range of 3.0 V to 5.5 V. It exhibits a typical propagation delay of 15 ns and functions reliably across an industrial temperature range of -40°C to +105°C. Packaged in a 20-lead SSOP, it combines signal isolation with power delivery in a compact form factor.

Feature Summary

• Integrates an isolated DC-to-DC converter for simultaneous signal and power transmission across the isolation barrier
• Utilizes silicon dioxide (SiO2) based magnetic coupling technology for high reliability and low skew
• Provides regulated output voltage capability from the internal converter to support downstream circuitry

Applications

• Industrial automation systems requiring galvanic isolation between control and sensor domains
• Medical equipment interfaces needing certified isolation barriers for patient safety
• Power electronics gate drive circuits where isolated power and signal integrity are critical

Procurement Notes

Verify the specific suffix (e.g., CRSZ vs. CRZ-RL7) against the manufacturer's datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status directly with the supplier or official documentation, as regulatory markings may vary by production batch. Ensure the source is an authorized distributor to guarantee component authenticity and traceability.

Selection Notes

Select this component when both bidirectional signal isolation and isolated power generation are required in a single package. Compare the 100 Mb/s data rate against higher-speed alternatives if system timing requirements exceed current capabilities. Evaluate the thermal performance of the SSOP-20 package against the expected power dissipation of the integrated converter under maximum load conditions.

Part Context

This part belongs to the ADuM521x family of isoPower digital isolators. It shares architectural similarities with the ADUM5210 and ADUM5211 but differs in channel count and specific pinout configurations. The family utilizes Analog Devices' proprietary capacitive and magnetic isolation technologies to achieve high common-mode transient immunity.

Replacement Considerations

Direct functional substitutes include the ADUM5210CRSZ and ADUM5211CRSZ, though pin compatibility and channel counts must be verified. Cross-reference with other isoPower series devices from Analog Devices for similar integration levels.
