**ADG5413BRUZ-REEL7: The Robust Quad SPST Switch for Demanding High-Voltage Environments**

In the realm of industrial automation, precision instrumentation, and test and measurement equipment, the ability to reliably switch high-voltage signals is paramount. The **ADG5413BRUZ-REEL7** from Analog Devices stands out as a premier solution, engineered to meet these rigorous demands. This high-performance, quad, single-pole/single-throw (SPST) switch integrates **advanced fault protection** and **exceptionally low on-resistance**, establishing a new benchmark for robustness and signal integrity in harsh electrical environments.

A defining feature of the ADG5413 is its **latch-up immune construction**. Utilizing a proprietary silicon-on-insulator (SOI) process, the device is inherently immune to the latch-up conditions that can plague conventional CMOS switches. This immunity is critical in systems where large transient signals or power supply fluctuations could cause catastrophic failure, thereby significantly enhancing system reliability and longevity.

The switch's **±60 V fault protection** on its source (S) and drain (D) pins provides an essential layer of security. In fault scenarios—such as a sensor failure or a disconnected cable where inputs can be driven beyond the supply rails—the ADG5413 robustly clamps these overvoltages without sustaining damage. This allows the system to continue normal operation once the fault condition is removed, preventing costly downtime and repairs. Furthermore, the device offers **overvoltage detection** logic flags for each channel, enabling the system microcontroller to instantly identify and respond to fault events.

Despite its high-voltage capabilities, the ADG5413 does not compromise on performance. It boasts a remarkably **low on-resistance of 35 Ω**, which remains flat across the entire signal range. This low and consistent resistance minimizes signal distortion and power loss, ensuring accurate transmission of both analog and digital signals—a crucial factor for data acquisition systems and automatic test equipment (ATE) where precision is non-negotiable.

Designed for flexibility, the switch operates with dual supplies from ±9 V to ±22 V or a single supply from 9 V to 40 V. ItsTTL/CMOS-compatible logic inputs simplify interface with modern controllers and FPGAs. The ADG5413BRUZ-REEL7 is offered in a compact 24-lead TSSOP package, making it suitable for space-constrained applications without sacrificing functionality.

**ICGOOODFIND:** The ADG5413BRUZ-REEL7 is an industry-leading high-voltage switch that masterfully combines **robust ±60 V fault protection**, **latch-up immunity**, and **low on-resistance**. It is an indispensable component for designers building reliable, high-precision systems in industrial, instrumentation, and communications infrastructure, where overcoming challenging signal conditions is a daily requirement.
