**The ADG408BR-REEL: A High-Performance 8-Channel CMOS Analog Multiplexer**

In the realm of precision signal routing and data acquisition systems, the selection of a multiplexer is a critical determinant of overall system performance. The **ADG408BR-REEL** stands out as a premier solution, an **8-channel single-ended analog multiplexer** designed to meet the stringent demands of high-accuracy applications. Fabricated on an advanced **CMOS process**, this integrated circuit offers a compelling combination of low power consumption, high switching speed, and exceptional signal fidelity.

The core function of the ADG408BR is to select one of eight independent analog input signals and connect it to a common output, based on a 3-bit binary address (A0, A1, A2). Its design is optimized for **bipolar and unipolar signals**, handling voltages that swing above and below ground, typically within the range of ±15 V. This wide supply voltage capability makes it exceptionally versatile for industrial, communication, and test equipment. A key feature is its **break-before-make switching action**, which prevents momentary shorting between channels during transition, thereby protecting delicate source circuitry.

Performance is where the ADG408BR-REEL truly excels. It exhibits an **ultra-low on-resistance of less than 100 Ω**, which remains remarkably flat across the entire analog signal range. This minimizes distortion and errors in the transmitted signal, a crucial factor for maintaining accuracy. Furthermore, it boasts very low leakage currents, typically in the nanoampere range, which is vital for applications involving high-impedance sources. The device also features **fast switching times (tON ~175 ns)** and minimal charge injection, ensuring that data acquisition systems can operate at higher speeds without introducing significant switching artifacts.

Housed in a compact 16-lead SOIC package, the ADG408BR-REEL is designed for space-constrained applications. Its **TTL and CMOS-compatible digital inputs** simplify interface with modern microcontrollers and digital signal processors, reducing the need for additional level-shifting circuitry. The "REEL" suffix indicates that it is supplied on a reel, making it perfectly suited for automated high-volume assembly processes.

**ICGOO FIND:** The ADG408BR-REEL is a high-reliability component that delivers superior analog performance in a robust package. It is an ideal choice for designers of data acquisition systems, audio and video routing, automatic test equipment (ATE), and industrial control systems where signal integrity, speed, and power efficiency are non-negotiable.
