**ADG201HSKRZ-REEL: Analog Devices' Precision CMOS Switch for High-Performance Signal Routing**

In the realm of high-precision signal chain design, the integrity of signal routing is paramount. Analog Devices Inc. (ADI) addresses this critical need with the **ADG201HSKRZ-REEL**, a monolithic **CMOS SPST (Single-Pole/Single-Throw) switch** engineered for applications where performance cannot be compromised. This component stands out as a superior solution for routing analog signals in test and measurement equipment, data acquisition systems, medical instrumentation, and audio routing systems.

The **ADG201HSKRZ-REEL** is designed on an advanced CMOS process, which is the foundation of its exceptional characteristics. It features **very low power consumption** and a high switching speed, making it ideal for portable, battery-operated devices and high-speed multiplexing applications. A key attribute of this switch is its **low on-resistance (typically 35Ω)**, which ensures minimal signal attenuation and distortion when the switch is closed. Furthermore, the flatness of this on-resistance across the input signal range is crucial for maintaining linearity and fidelity in precision systems.

Another significant advantage is its **excellent off-isolation and low charge injection**. High off-isolation prevents unwanted signal leakage from turned-off switches from corrupting the desired signal path, a critical factor in maintaining channel separation in multiplexed systems. The low charge injection is vital for preserving the accuracy of held voltages in sample-and-hold circuits and successive-approximation register (SAR) ADC interfaces, as it minimizes voltage glitches during switching transitions.

Housed in a space-saving **16-lead SK package**, the device is offered in a reel format (-REEL) for high-volume, automated manufacturing. It operates from a **single supply voltage ranging from +10.8 V to +16.5 V** or dual supplies from ±5 V to ±8 V, providing design flexibility for various system-level requirements. The robust design ensures **latch-up immunity** and ESD protection, enhancing reliability in demanding environments.

ICGOODFIND: The ADG201HSKRZ-REEL from Analog Devices exemplifies the pinnacle of precision switching technology. Its combination of low on-resistance, high speed, and excellent isolation characteristics makes it an indispensable component for designers who demand uncompromising signal integrity and reliability in their high-performance systems.
