**ADG5409BRUZ-REEL7: High-Performance 4-Channel Multiplexer for Precision Signal Routing Applications**

In the realm of precision electronics, the accurate routing of analog signals is a critical requirement across a wide array of applications, from automated test equipment (ATE) and data acquisition systems to medical instrumentation and communication infrastructure. The **ADG5409BRUZ-REEL7** from Analog Devices stands out as a premier solution, engineered to meet the stringent demands of these high-performance environments. This 4-channel single-pole/double-throw (SPDT) analog multiplexer integrates advanced design and process technology to deliver exceptional signal integrity, reliability, and versatility.

At the core of the ADG5409's performance is its **low on-resistance (Ron) of just 2.5 Ω**, a feature that is remarkably consistent across the entire analog input range. This minimal resistance is crucial as it ensures negligible voltage drop and signal attenuation, preserving the accuracy of the transmitted signal. Furthermore, the device exhibits an **ultra-flat on-resistance profile**, which remains stable across the specified analog voltage range. This characteristic is vital for applications requiring high linearity and minimal distortion, such as precision measurement and audio signal routing.

Another defining attribute of the ADG5409 is its **break-before-make switching action**. This built-in feature prevents momentary shorting between channels during switching transitions, thereby protecting delicate downstream components and ensuring system safety and integrity. The multiplexer is designed for bipolar operation, supporting both positive and negative signal swings with a wide supply range from ±5 V to ±22 V, or a single supply from 8 V to 44 V. This flexibility makes it suitable for a broad spectrum of signal levels, from standard industrial ±10 V inputs to higher voltage applications.

The device also boasts **excellent dynamic performance**. With very low charge injection and low parasitic capacitances, the ADG5409 minimizes transients and settling time glitches that can corrupt fast-switching signals. This results in cleaner switching and higher throughput in high-speed data acquisition systems. Its robust architecture ensures **latch-up immunity** under any circumstance, a critical reliability feature in complex systems where power sequencing might not be perfectly controlled.

Housed in a compact 16-lead TSSOP package, the ADG5409BRUZ-REEL7 is supplied in a reel format optimized for high-volume automated manufacturing. Its combination of high performance, robustness, and integration makes it an ideal choice for designers looking to enhance signal routing precision without compromising on board space or system reliability.

**ICGOODFIND**: The ADG5409BRUZ-REEL7 is a superior 4-channel multiplexer that sets a high standard for precision signal routing. Its exceptional combination of **ultra-low and flat on-resistance**, wide voltage range, robust switching protection, and excellent dynamic performance makes it an indispensable component for designing accurate and reliable systems in test, measurement, and medical fields.
