**ADG411BR: High-Performance, Low-Voltage 4-Channel Analog Multiplexer**

In the realm of precision signal routing and data acquisition systems, the selection of an appropriate analog switch is paramount. The **ADG411BR** stands out as a premier solution, engineered to meet the rigorous demands of modern low-voltage, high-performance applications. This monolithic CMOS device integrates four independently selectable switches, offering designers a compact and reliable method for managing multiple analog signals with exceptional accuracy.

A defining characteristic of the ADG411BR is its **low power consumption and operation from a single +3 V to +5.5 V supply**, making it exceptionally well-suited for battery-powered and portable equipment. This feature is critical in extending operational life in devices where energy efficiency is a primary concern. Furthermore, the multiplexer boasts **very low on-resistance (typically 25 Ω)**, which is remarkably flat across the entire input signal range. This minimizes signal distortion and ensures that the integrity of the analog signal is preserved during switching, a vital attribute for precision measurement and audio applications.

The device also features **fast switching speeds and break-before-make switching action**. This design prevents momentary shorting between channels during transition, enhancing system safety and reliability. The TTL/CMOS-compatible digital inputs simplify interface with modern microcontrollers and digital signal processors (DSPs), facilitating easy integration into complex digital systems.

Applications for the ADG411BR are vast and varied. It is ideally deployed in **battery-operated systems, medical instrumentation, communication infrastructure, and automated test equipment (ATE)**. Its ability to accurately route low-level signals without introducing significant error makes it a cornerstone in designing sensitive measurement systems.

ICGOOODFIND: The ADG411BR is a robust, high-integration analog multiplexer that delivers superior performance through its low on-resistance, low power operation, and seamless digital control, making it an optimal choice for space-constrained and power-sensitive designs.
