**ADG5213BRUZ: A Comprehensive Technical Overview of the High-Voltage, Latch-Up Immune, Dual SPST Analog Switch**

In the realm of precision signal routing and system protection, the **ADG5213BRUZ from Analog Devices** stands out as a robust and highly reliable solution. This integrated circuit is a **high-voltage, latch-up immune, dual single-pole/single-throw (SPST) analog switch** engineered to meet the demanding requirements of industrial, instrumentation, and automotive applications. Its design prioritizes **exceptional signal integrity**, **robust protection**, and **operational resilience** in harsh electrical environments.

A defining characteristic of the ADG5213BRUZ is its ability to handle **bipolar analog signals with ease**. It supports a wide supply voltage range from ±5 V to ±22 V, or a single supply from 8 V to 44 V. This high-voltage capability makes it perfectly suited for interfacing with sensors, driving actuators, and switching signals in **±15 V analog systems**, which are commonplace in industrial control and test and measurement equipment.

The switch's architecture is fundamentally designed for **superior on-performance**. When conducting a signal, it exhibits a very **low on-resistance (typically 60 Ω)** that remains flat across the entire analog input range. This low and consistent resistance is critical for minimizing signal distortion and power loss, ensuring that the voltage being switched is passed through with high fidelity. Complementing this is its **ultra-low leakage current**, measured in mere nanoamperes, which is vital for maintaining accuracy in high-impedance circuits and precision measurement systems.

Perhaps one of its most critical features is its **latch-up immunity**. The ADG5213BRUZ is fabricated on Analog Devices' proprietary iCMOS® (industrial CMOS) process technology. This advanced manufacturing technique not only enables high-voltage operation and low power consumption but also **eliminates the possibility of latch-up**, a destructive parasitic SCR effect that can be triggered by voltage spikes beyond the supply rails. This inherent robustness provides a significant layer of protection, allowing the switch to survive **overvoltage fault conditions up to ±55 V** at its input pins, even when the power supplies are absent. This feature is indispensable for applications where unexpected transients are a constant threat.

The device integrates two independently controllable SPST switches, offering design flexibility for enabling or isolating two separate signal paths. It features **TTL and CMOS-compatible digital logic inputs**, simplifying interface with modern microcontrollers and FPGAs without requiring level-shifting circuitry. Housed in a compact 16-lead TSSOP package, the ADG5213BRUZ provides a powerful combination of performance and space efficiency.

**ICGOODFIND**: The ADG5213BRUZ is an exemplary analog switch that delivers **high-voltage switching**, **uncompromising signal fidelity**, and **robust latch-up immune protection**. Its ability to reliably operate and protect downstream circuitry in the presence of large fault signals makes it an superior choice for designing resilient and accurate electronic systems in challenging environments.
