ADUM5212BRSZ

Overview

The ADUM5212BRSZ is a dual-channel digital isolator from Analog Devices, featuring integrated DC-to-DC converters for power delivery across isolation barriers. It operates within a supply voltage range of 3.135 V to 5.5 V and supports data rates up to 25 Mbps with a propagation delay of 15 ns. The device provides 2500 Vrms insulation strength and exhibits a common-mode transient immunity of 25 kV/µs. Designed for robust signal transmission, it functions reliably across an operating temperature range of -40°C to +105°C and is housed in a 20-pin SSOP package.

Feature Summary

• Integrates isolated DC-to-DC converters to provide power to the secondary side without external magnetic components
• Utilizes capacitive coupling technology to achieve high-speed digital signal isolation with low latency
• Offers enhanced system accuracy by eliminating galvanic connections between isolated circuits

Applications

• Industrial automation systems requiring reliable sensor isolation
• Medical equipment needing strict patient safety isolation standards
• Power metering applications involving high-voltage measurement

Procurement Notes

Verify the specific suffix (e.g., BRSZ) against official Analog Devices documentation to confirm pinout compatibility and packaging type. Ensure that the integrated DC-DC converter requirements align with your system's power budget and noise sensitivity specifications before finalizing procurement decisions.

Selection Notes

Select this component when dual-channel isolation with integrated power conversion is required. Compare performance metrics such as CMTI and propagation delay against alternative isolators to ensure compatibility with high-speed communication protocols. Validate thermal management capabilities given the internal power generation of the DC-DC converter.

Part Context

This part belongs to the ADuM521x family of dual-channel isolators with integrated power. It serves as a solution for replacing traditional optocouplers in applications demanding higher reliability, lower power consumption, and improved signal integrity. The series is widely used in industrial and medical sectors where robust isolation is critical.

Replacement Considerations

Check for direct replacements within the ADuM521x series or newer generations from Analog Devices. Verify pin-to-pin compatibility and electrical parameter equivalence before substituting.
