**ADG812YRUZ: A High-Performance, 5 Ω SPST Analog Switch for Precision Signal Routing**
In the realm of modern electronic design, the accurate and reliable routing of analog signals is paramount. The **ADG812YRUZ from Analog Devices** stands out as a critical component engineered to meet this exacting demand. This monolithic CMOS device is a **single-pole/single-throw (SPST) analog switch** renowned for its exceptionally low on-resistance and high performance, making it an ideal solution for a wide array of precision applications, from test and measurement equipment to data acquisition systems and audio signal routing.
The defining feature of the ADG812YRUZ is its **ultra-low on-resistance (RON) of just 5 Ω typical**. This characteristic is crucial as it minimizes signal attenuation and distortion when the switch is closed, ensuring that the integrity of even the most delicate analog signals is preserved. The low on-resistance is exceptionally flat across the entire analog input range, which is vital for maintaining **superior linearity and low total harmonic distortion (THD)**. Furthermore, the device operates from a single **1.8 V to 5.5 V supply**, making it perfectly suited for both portable, battery-powered devices and larger systems where power efficiency is a concern.
The ADG812YRUZ is designed for break-before-make switching action, preventing momentary shorting between signal paths during switching transitions. Its fast switching speeds, with ton and toff typically at 20 ns and 13 ns respectively, enable it to handle high-speed multiplexing tasks with ease. The chip is also characterized by its **high current handling capability of up to 200 mA continuous**, which expands its utility beyond small-signal processing to include power management and load switching functions.
Housed in a compact **16-lead TSSOP package**, the ADG812YRUZ offers a small footprint for space-constrained PCB designs. Its robust construction ensures **latch-up immunity** and provides ESD protection of up to 2 kV per the human body model, safeguarding the device and the system from electrostatic discharge events. This combination of high performance, reliability, and integration makes it an indispensable component for designers seeking to optimize their signal chains.
**ICGOODFIND:** The ADG812YRUZ is a premier solution for designers prioritizing signal fidelity and integration. Its blend of **5 Ω on-resistance**, broad supply voltage compatibility, high current handling, and robust packaging establishes it as a top-tier choice for precision signal routing in demanding applications.
