**ADG1407BRUZ: A Comprehensive Technical Overview of Analog Devices' Precision 16-Channel Multiplexer**
In the realm of precision signal routing and data acquisition systems, the multiplexer (MUX) serves as a critical component, determining the integrity and accuracy of the measured signal. The **ADG1407BRUZ from Analog Devices** stands as a premier solution in this category, representing a high-performance, **16-channel single-ended analog multiplexer** designed for the most demanding applications. This article provides a detailed technical examination of its architecture, key features, and ideal use cases.
Constructed on Analog Devices' proprietary iCMOS® (industrial CMOS) process technology, the ADG1407BRUZ achieves a remarkable synergy of high performance and low power consumption. This process enables the device to operate across a wide supply range, from **±5 V to ±22 V for dual supplies** or from +8 V to +44 V for a single supply, making it exceptionally versatile for various industrial and instrumentation setups. A fundamental metric for any multiplexer is its on-resistance (RON), and the ADG1407BRUZ excels with a very low and flat RON of typically 2.5 Ω. The **minimal RON flatness** ensures significantly reduced distortion when switching signals, which is paramount for maintaining signal fidelity.
Another cornerstone of its precision is its exceptional leakage performance. The device boasts an ultra-low **leakage current of merely 100 pA at 25°C**, a critical characteristic for applications involving high-source impedances or where minimizing signal bleed-through is essential. Furthermore, the ADG1407BRUZ features **break-before-make switching action**, a vital protective measure that prevents momentary shorting between channels during transition, thereby safeguarding both the multiplexer and the source signals.
The device integrates a 4-bit binary decoder alongside the 16 channels, simplifying the digital interface. The channel selection is controlled via the A0, A1, A2, and A3 address lines and an enable (EN) pin, allowing for straightforward interfacing with microcontrollers, DSPs, or FPGAs. Housed in a compact 28-lead TSSOP package, the ADG1407BRUZ is engineered for space-constrained PCB designs while ensuring robust thermal performance.
Typical applications that benefit from its capabilities include:
* **Precision Data Acquisition Systems (DAQ)**
* **Automated Test Equipment (ATE)**
* **Medical Instrumentation** (e.g., patient monitoring, MRI systems)
* **Audio and Video Signal Routing**
* **Communication Infrastructure**
**ICGOODFIND:** The ADG1407BRUZ is a top-tier 16-channel analog multiplexer that sets a high standard for precision signal switching. Its combination of **extremely low on-resistance, minimal power consumption, wide voltage range, and superior channel isolation** makes it an indispensable component for design engineers who cannot compromise on signal accuracy and system reliability. It is an optimal choice for advanced industrial, medical, and test and measurement systems.
