**ADG413BNZ: High Performance, Latch-Up Immune, ±15 V/+12 V iCMOS Quad SPST Switch**

In the realm of precision signal switching and routing, the **ADG413BNZ** stands out as a premier solution engineered for demanding applications. This device is a **quad single-pole/single-throw (SPST) switch** fabricated on Analog Devices' proprietary **iCMOS® (industrial CMOS) process technology**. This advanced manufacturing technique enables a unique combination of high performance, low power consumption, and robust operation across a wide voltage range.

A defining characteristic of the ADG413BNZ is its **exceptional latch-up immunity**. Traditional CMOS devices are susceptible to latch-up, a destructive high-current state triggered by voltage spikes beyond the supply rails. The iCMOS construction effectively eliminates this threat, ensuring reliable operation and protecting both the switch and the surrounding circuitry in electrically harsh environments. This robustness is further complemented by its ability to handle **bipolar analog signals up to ±15 V** and digital logic signals with supplies as low as +12 V, making it incredibly versatile for mixed-signal systems.

The performance metrics of this switch are impressive. It features **very low on-resistance (typically 35 Ω)** that remains flat across the entire analog signal range, minimizing distortion and power loss. Coupled with **ultra-low leakage currents (sub-nanoampere levels)**, it guarantees high signal fidelity and accuracy, which is critical for precision measurement equipment, data acquisition systems, and medical instrumentation. The fast switching speeds further enhance its capability in automated test equipment and communication systems where signal integrity and speed are paramount.

Each of the four independent switches is controlled by a TTL/CMOS-compatible digital input, simplifying interface with microcontrollers, FPGAs, and DSPs. The ADG413BNZ is offered in a compact 16-lead package, making it suitable for space-constrained PCB designs without compromising on functionality or performance.

**ICGOOODFIND**: The ADG413BNZ is a superior quad SPST switch that delivers **high-voltage handling, flawless signal integrity, and ultimate reliability**. Its **latch-up immune iCMOS design** makes it an indispensable component for designers building robust, high-performance systems in industrial, automotive, and communications applications.
