ADUM4153BRIZ

Overview

The ADUM4153BRIZ is a seven-channel digital isolator from Analog Devices, designed for isolated serial peripheral interface (SPI) applications. It operates on a single supply voltage ranging from 3V to 5.5V and utilizes a 20-lead SOIC package with a width of 7.50mm. The device supports SPI clock speeds up to 17 MHz and offers a data rate of 34 Mbps. It provides high common-mode transient immunity of 25 kV/µs and an isolation rating of 5000 Vrms. The operating temperature range extends from -40°C to 125°C.

Feature Summary

• Optimized for isolated SPI interfaces with efficient channel isolation
• High common-mode transient immunity ensures reliable signal integrity
• Supports high-speed SPI clock operations up to 17 MHz

Applications

• Isolated serial peripheral interface systems
• Industrial automation control networks
• Medical equipment requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'BRIZ' corresponds to the 20-SOIC package and tape & reel packaging configuration. Confirm that the manufacturer's lead time aligns with project schedules, as standard lead times may apply. Ensure the component status is listed as active in official catalogs before finalizing procurement orders to avoid obsolescence risks.

Selection Notes

Select this component when designing systems requiring isolation for multiple SPI lines within a compact footprint. The 20-lead SOIC package suits surface-mount assembly processes. Consider the 3V to 5.5V supply range compatibility with existing logic levels. The high CMTI rating makes it suitable for noisy industrial environments where signal integrity is critical.

Part Context
