**ADG719BRM: A Comprehensive Technical Overview of this CMOS SPDT Analog Switch**

The **ADG719BRM** from Analog Devices represents a highly integrated, monolithic **CMOS Single-Pole Double-Throw (SPDT) analog switch**, engineered to deliver exceptional performance in a wide array of signal routing applications. Housed in a compact 8-pin MSOP package, this device is designed for systems where space, precision, and low power consumption are critical.

At its core, the switch utilizes advanced **CMOS technology**, which is fundamental to its impressive characteristics. This technology enables **ultra-low power consumption**, typically less than 0.01 µW, making it ideal for battery-powered and portable equipment. Furthermore, it ensures a very high off-isolation and minimal charge injection, which are vital parameters for maintaining signal integrity, especially when switching high-precision analog signals and sampling in data acquisition systems.

A key feature of the ADG719BRM is its **broad voltage supply range**, operating from a single supply of +1.8 V to +5.5 V. This flexibility allows it to interface seamlessly with both modern low-voltage logic and legacy 5 V systems, providing significant design versatility. The device offers **low on-resistance (RON)** of typically 2.5 Ω, which remains exceptionally flat across the entire signal range. This low and linear RON is crucial as it minimizes signal distortion and power loss, ensuring that the switched signal is passed through with high fidelity.

The switching performance is equally robust, featuring **fast switching times** of tON = 14 ns and tOFF = 6 ns. This high-speed operation is essential for applications requiring rapid channel multiplexing, such as in communications systems and high-speed data routers. The ADG719BRM is also designed with **TTL/CMOS compatible digital inputs**, simplifying interface with microcontrollers, FPGAs, and digital logic circuits without requiring additional level-shifting components.

**ICGOOODFIND**: The ADG719BRM stands out as an optimal solution for precision signal routing, offering an outstanding combination of low on-resistance, fast switching, minimal power consumption, and broad supply voltage operation in a miniature package.
