ADUM3153ARSZ

Overview

The ADUM3153ARSZ is a seven-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four high-speed channels supporting up to 17 MHz SPI clock speeds and three auxiliary channels operating at 250 kbps. The device provides 3750 Vrms isolation voltage with a common-mode transient immunity of 25 kV/µs. It operates within a supply voltage range of 3 V to 5.5 V and functions across an industrial temperature range of -40°C to +125°C. Packaged in a 20-lead SSOP.

Feature Summary

• Integrates four high-speed data channels optimized for low propagation delay SPI signal isolation
• Includes three auxiliary channels suitable for non-timing-critical control functions
• Employs chip-level magnetic coupling transformer technology for robust galvanic isolation

Applications

• Isolation for Serial Peripheral Interface (SPI) communication links
• Industrial process control systems requiring multi-channel signal separation
• Medical equipment interfaces demanding high isolation safety standards

Procurement Notes

Verify the specific suffix ARSZ corresponds to the SSOP-20 tube packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure compatibility with JEDEC standard pad layouts if utilizing evaluation boards such as EVAL-ADUM3151Z. Check humidity sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when designing SPI-based systems requiring seven isolated channels. The combination of four high-speed and three lower-speed channels offers flexibility for complex peripheral management. Consider the 3750 Vrms rating for applications needing significant potential difference separation between domains.
