**The ADG738BRU: A High-Performance, Low-Voltage 8-Channel CMOS Analog Multiplexer**

In the realm of precision electronic systems, the ability to accurately route analog signals is paramount. The **ADG738BRU from Analog Devices** stands out as a critical component in achieving this, representing a significant advancement in multiplexer technology. This integrated circuit is an **8-channel single-ended analog multiplexer** designed to meet the rigorous demands of modern, power-sensitive applications that operate on low-voltage supplies.

Engineered with a **low-voltage CMOS process**, the ADG738BRU is optimized for operation from a single **+1.8 V to +5.5 V supply**, making it exceptionally versatile. This wide supply range allows it to interface seamlessly with both modern low-voltage microcontrollers, FPGAs, and older 5V systems, providing a crucial bridge in mixed-voltage environments. A key to its high performance is its **low on-resistance of just 2.5 Ω**, which remains exceptionally flat across the entire analog input range. This minimal and consistent resistance ensures negligible signal distortion and voltage drop, preserving the integrity of the transmitted analog signal.

Beyond its low resistance, the ADG738BRU excels in power management. It features an **ultra-low power consumption**, typically drawing less than 4 nA, which is indispensable for battery-powered and portable devices where every microwatt counts. The device also boasts **fast switching speeds** (ton typically 28 ns) and high bandwidth, enabling it to handle rapid signal changes in data acquisition systems without introducing significant delay or distortion.

The architecture of the ADG738BRU includes three digital address lines (A0, A1, A2) and an enable pin, offering straightforward binary control to select any one of the eight channels. It is designed with **break-before-make switching action**, a vital feature that prevents momentary shorting between adjacent channels during switching, thereby protecting delicate signal sources. Housed in a compact TSSOP-16 package, it provides an excellent solution for space-constrained PCB designs.

Typical applications are vast and include:

* **Precision Data Acquisition Systems (DAQ)**

* **Battery-Powered Medical Instrumentation**

* **Audio and Video Signal Routing**

* **Automated Test Equipment (ATE)**

* **Communication Infrastructure**

**ICGOODFIND:** The ADG738BRU is a superior choice for designers seeking a reliable, high-performance analog multiplexer. Its combination of **extremely low on-resistance, wide voltage range, minimal power consumption, and robust packaging** makes it an indispensable component for enhancing signal integrity and efficiency in a wide array of advanced electronic systems.
