**ADG5404BRUZ-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 for systems ranging from automated test equipment (ATE) and data acquisition (DAQ) systems to medical instrumentation and industrial control. The **ADG5404BRUZ-REEL7** from Analog Devices stands out as a premier solution, engineered to deliver exceptional performance in these demanding applications. This 4-channel single-pole/double-throw (4x SPST) multiplexer integrates robust protection and high fidelity into a compact form factor, making it an ideal choice for designers who cannot compromise on signal integrity.
A defining characteristic of the ADG5404BRUZ-REEL7 is its **low on-resistance of just 2.5 Ω**, which remains exceptionally flat across the entire analog input range. This minimal and stable resistance is crucial as it minimizes signal attenuation and distortion, ensuring that the amplified or measured signal at the output is a true representation of the input. Furthermore, the device boasts an impressive **on-resistance flatness of only 0.5 Ω**, a key parameter for maintaining linearity in precision applications.
Beyond its excellent conductive properties, the ADG5404BRUZ-REEL7 is built for resilience in harsh electrical environments. It features **integrated, robust overvoltage protection up to ±55 V**, which safeguards not only the multiplexer itself but also the sensitive downstream components (like analog-to-digital converters or amplifiers) from damaging voltage transients that can occur in industrial settings. This protection remains active even when the supply pins are unpowered (0 V), a significant advantage for fault-tolerant systems. Additionally, the device offers **latch-up immunity based on the proprietary iCMOS® process technology**, ensuring reliable operation and preventing catastrophic failure.
The multiplexer operates over a wide supply range from ±5 V to ±22 V, providing designers with the flexibility to interface with a variety of signal levels. Its architecture ensures **break-before-make switching action**, eliminating momentary shorting between channels during transition and further protecting the integrity of the signals being routed. Housed in a space-saving 16-lead TSSOP package, the device is also well-suited for applications where board real estate is at a premium.
ICGOOODFIND: The ADG5404BRUZ-REEL7 establishes itself as a superior 4-channel multiplexer by combining high-performance switching, **exceptional signal fidelity** through low and flat on-resistance, and **unmatched system protection** against overvoltage and latch-up events. It is an indispensable component for any design requiring precision, reliability, and robustness in analog signal routing.
