ADUM4153ARIZ

Overview

The ADUM4153ARIZ is a seven-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000 Vrms isolation voltage with a data rate of 34 Mbps and a typical propagation delay of 24 ns. The device operates on a single 3 V to 5.5 V supply, consumes 5 mA on the input side and 6.5 mA on the output side, and functions within a temperature range of -40°C to +125°C in a 20-pin SOIC package.

Feature Summary

• Integrates seven independent unidirectional channels for high-density signal isolation.
• Employs on-chip miniaturized transformers for robust magnetic coupling isolation.
• Features integrated DC-DC converter capability for isolated power delivery.
• Provides high common-mode transient immunity for reliable noise rejection.

Applications

• SPI interface isolation
• Industrial process control systems
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix 'ARIZ' to confirm the 20-SOIC package and lead-free RoHS compliance status. Confirm that the required data rate of 34 Mbps aligns with system timing requirements. Ensure the 5000 Vrms isolation rating meets safety standards for the intended application environment.

Selection Notes

Select this component when seven isolated channels are required within a compact footprint. The 34 Mbps speed supports high-frequency SPI communication. Consider the 20-SOIC package dimensions for PCB layout constraints. Verify that the 5 mA input current consumption fits the power budget of the source circuit.
