**ADG904BRU: A 5 Ω On-Resistance, 4-Channel CMOS Multiplexer for High-Performance RF and Precision Signal Switching**
In the realm of modern electronic design, the demand for efficient and reliable signal routing solutions is paramount, especially in applications involving high-frequency RF signals and precision analog measurements. The **ADG904BRU** stands out as a critical component engineered to meet these rigorous demands. This device is a **4-channel single-pole/single-throw (SPST) CMOS multiplexer** that integrates four independently selectable switches into a compact package, offering designers a versatile tool for complex signal switching tasks.
A defining feature of the ADG904BRU is its **extremely low on-resistance (Ron) of just 5 Ω**. This characteristic is crucial as it minimizes signal attenuation and power loss when the switch is closed, ensuring that the integrity of both high-frequency and low-level analog signals is preserved. The flatness of this on-resistance across the input signal range is also exceptional, which is vital for maintaining low distortion in precision applications. Furthermore, the device operates from a **single 3 V to 5.5 V supply**, making it compatible with a wide array of modern digital systems and portable, battery-operated equipment.
The architecture of the ADG904BRU is tailored for **high-performance RF switching**. It boasts a wide -3 dB bandwidth that exceeds 200 MHz, enabling it to handle signals well into the RF spectrum with minimal insertion loss. This makes it an ideal choice for wireless communication systems, RF test instrumentation, and RF front-end modules where signal fidelity is non-negotiable. The CMOS construction ensures **ultra-low power consumption and high isolation** between channels, preventing crosstalk and interference that could degrade system performance.
Beyond RF, the multiplexer excels in **precision DC and analog signal routing**. Its low charge injection and high off-isolation characteristics make it suitable for data acquisition systems, medical imaging equipment, and automated test equipment (ATE), where accurately switching sensitive signals between multiple sources or destinations is required. The robust design ensures reliable operation and a long operational lifespan.
Housed in a space-saving 16-lead TSSOP package, the ADG904BRU offers an optimal balance of performance and board space efficiency. Its digital control interface is simple, requiring a standard CMOS/TTL compatible input for seamless integration with microcontrollers, FPGAs, and DSPs.
**ICGOO**DFIND: The ADG904BRU is a superior 4-channel CMOS multiplexer that sets a high standard for **low on-resistance and high-bandwidth performance**. It is an indispensable component for designers tackling the challenges of **high-frequency RF systems and precision analog switching**, delivering a combination of low power, high integration, and signal integrity that is critical for advanced electronic applications.
