**High-Performance Signal Routing with the ADG413BN Quad SPST CMOS Switch**

In the design of modern electronic systems, from precision instrumentation to automated test equipment, the ability to accurately and reliably route analog and digital signals is paramount. The **ADG413BN**, a monolithic quad single-pole/single-throw (SPST) switch fabricated on an advanced CMOS process, stands out as a critical component for achieving this high-performance signal routing.

The device integrates four independent switches, offering designers exceptional flexibility. Each switch features **low on-resistance of less than 35Ω**, which is remarkably consistent across the analog input range. This low and flat resistance is crucial as it minimizes signal attenuation and distortion, ensuring the integrity of the passed signal is maintained. This makes the ADG413BN exceptionally well-suited for routing precision analog signals in data acquisition systems, sample-and-hold circuits, and audio switching applications.

A key advantage of the CMOS construction is the device's extremely low power consumption. It operates from a single supply ranging from **+5 V to ±15 V**, accommodating a wide variety of system-level requirements. Furthermore, the ADG413BN features **fast switching speeds**, with turn-on and turn-off times typically under 150 ns. This rapid switching capability is essential for applications requiring multiplexing of signals at higher frequencies, maximizing system throughput without introducing significant delays.

Beyond its electrical performance, the ADG413BN is engineered for robustness. It utilizes **latch-up immune CMOS technology**, a vital feature that prevents the destructive latch-up phenomenon that can occur in harsh electrical environments. This inherent ruggedness, combined with its **break-before-make switching action**, ensures that momentary short circuits between channels are avoided during the switching process, protecting both the switch itself and the sensitive circuitry it is connected to.

The device is offered in a compact plastic DIP or SOIC package, making it suitable for space-constrained PCB designs. Its combination of low on-resistance, fast switching, and versatile power supply operation establishes the ADG413BN as a reliable and high-performance solution for a broad spectrum of signal routing challenges.
