**The ADG733BRU: A 5 Ω CMOS Low Voltage 4-Channel Multiplexer**

In the realm of analog signal routing and data acquisition systems, the performance of a multiplexer is paramount. The **ADG733BRU** stands out as a critical component, engineered to deliver exceptional signal integrity and robust performance in space-constrained, power-sensitive applications. This integrated circuit is a **monolithic CMOS device** containing four independently selectable single-pole/double-throw (SPDT) switches. Its defining characteristic is an ultra-low **on-resistance (RON) of just 5 Ω**, a feature that minimizes signal attenuation and distortion, making it ideal for precision analog systems.

A key advantage of the ADG733BRU is its **optimization for low-voltage operation**, functioning seamlessly with supplies from **+1.8 V to +5.5 V**. This broad range ensures compatibility with modern digital logic and low-power microcontrollers, facilitating design in portable, battery-operated devices such as medical instrumentation, communication systems, and automated test equipment. The CMOS construction is instrumental in achieving not only low power dissipation but also high switching speeds and minimal charge injection, which is crucial for maintaining accuracy in sample-and-hold circuits.

The device integrates four channels into a compact TSSOP-16 package, offering a high level of functional integration that simplifies PCB layout and reduces overall system footprint. Each switch handles analog signals that span from rail to rail, ensuring maximum dynamic range. Furthermore, the ADG733BRU features **break-before-make switching action**, preventing momentary shorting between channels during transition and enhancing system safety and reliability.

**ICGOOODFIND**: The ADG733BRU is a superior solution for designers seeking a combination of low on-resistance, low voltage operation, and high integration. Its 5 Ω RON ensures minimal signal loss, while its versatile power supply range makes it a cornerstone component for advancing precision in modern, portable electronic designs.
