**ADG1438BRUZ-REEL7: Precision Quad SPST Switch for High-Performance Signal Routing**
In the realm of advanced electronic systems, the accurate and reliable routing of signals is paramount. The **ADG1438BRUZ-REEL7** stands out as a critical component engineered to meet this exacting demand. This device is a monolithic, complementary metal-oxide semiconductor (CMOS) integrated circuit containing four independently selectable single-pole/single-throw (SPST) switches. Designed for precision performance, it serves as an ideal solution in a wide array of applications, from automated test equipment (ATE) and data acquisition systems to audio and video routing.
A key attribute of the **ADG1438BRUZ-REEL7** is its **exceptional low on-resistance of just 0.5 Ω**, which remains remarkably flat across the entire analog input range. This characteristic is vital for minimizing signal distortion and power loss, ensuring that the integrity of even the most sensitive signals is preserved during switching operations. Coupled with an ultra-low on-resistance flatness of 0.2 Ω, the switch guarantees highly linear performance, which is indispensable for high-fidelity audio and precision measurement applications.
The device operates over a broad **dual-supply range of ±5 V to ±22 V or a single-supply range of 8 V to 44 V**, offering designers significant flexibility in system power architecture. This wide voltage range makes it suitable for interfacing with both high-voltage industrial sensors and lower-voltage signal chains. Furthermore, the **ADG1438BRUZ-REEL7** features **break-before-make switching action**, a critical safety function that prevents momentary shorting between channels during switching transitions, thereby protecting downstream circuitry.
Another standout feature is its **latch-up immune construction**. Built on an advanced iCMOS® (industrial CMOS) process, the switch is inherently robust against latch-up, a common failure mode in CMOS devices that can be triggered by voltage surges beyond the supply rails. This inherent ruggedness ensures reliable operation in electrically noisy environments, enhancing system longevity and stability.
The part is offered in a compact 16-lead TSSOP package and is available in a tape and reel (REEL7) packaging format, making it optimized for high-volume, automated manufacturing processes. Its combination of precision, versatility, and robustness establishes the ADG1438BRUZ-REEL7 as a premier choice for designers who cannot compromise on signal path performance.
**ICGOODFIND:** The ADG1438BRUZ-REEL7 is a high-performance, precision quad SPST switch that excels in demanding signal routing applications. Its ultra-low and flat on-resistance, wide supply range, and robust iCMOS® construction make it an indispensable component for achieving superior signal integrity and system reliability in industrial, test, and measurement, and communication systems.
