**ADG633YRU: A High-Performance Quad SPST CMOS Switch for Precision Signal Routing Applications**

In the realm of modern electronic design, the accurate routing of precision analog and digital signals is a fundamental requirement across a vast array of applications, from automated test equipment and medical instrumentation to data acquisition systems. The **ADG633YRU** stands out as a premier solution, a quad, single-pole/single-throw (SPST) CMOS switch engineered to deliver exceptional performance where signal integrity is paramount.

This monolithic IC integrates four independently controllable switches, offering designers compactness and flexibility. Fabricated on an advanced CMOS process, the ADG633YRU is designed to operate from a single supply voltage ranging from **+1.8 V to +5.5 V**, making it ideally suited for both **3 V and 5 V systems**, including portable, battery-powered devices. A key feature is its **break-before-make switching action**, which prevents momentary shorting between channels during the switching process, a critical safeguard for sensitive downstream components.

The performance metrics of the ADG633YRU are what truly define it as a high-performance component. It exhibits an extremely low on-resistance (Ron) of just **4.5 Ω (typical)** with exceptional flatness across the specified signal range. This low and linear Ron ensures minimal voltage drop and distortion of the switched signal, preserving accuracy. Furthermore, it boasts **ultra-low power consumption and leakage currents**, characteristics inherent to its CMOS design. This results in negligible power dissipation and prevents signal leakage from degrading measurement precision.

For applications involving analog signals, the switch's performance is equally impressive. It offers a wide **-3 dB bandwidth typically exceeding 200 MHz**, enabling the routing of high-frequency signals without significant attenuation. The total harmonic distortion (THD) is also remarkably low, ensuring that audio or other precision analog signals pass through the switch with minimal introduction of spurious noise.

The robust design of the ADG633YRU is evident in its **latch-up immune construction**, which provides protection against the damaging effects of voltage surges. Housed in a space-saving 16-lead TSSOP package, it is designed for reliability in demanding industrial environments.

ICGOOODFIND: The **ADG633YRU** establishes itself as an industry benchmark for precision signal routing, masterfully balancing **low on-resistance, wide bandwidth, and minimal power consumption** in a versatile quad SPST configuration. Its ability to maintain signal fidelity makes it an indispensable component for designers who cannot compromise on accuracy.
