**REF192GRUZ: A Precision 3.096V Voltage Reference for Demanding Applications**
In the realm of high-precision electronics, system performance is often dictated by the stability and accuracy of its most fundamental components. Among these, the voltage reference stands as a critical pillar, setting the benchmark for accuracy in analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and precision measurement equipment. The **REF192GRUZ** from Analog Devices exemplifies this role, offering an exceptional blend of precision, stability, and low power consumption for the most demanding applications.
The REF192GRUZ is a **buried zener-based voltage reference** that provides a fixed, precise output of **3.096V**. This specific voltage is particularly valuable in systems interfacing with high-resolution data converters, serving as a stable full-scale reference. Unlike less advanced references, the REF192's core technology ensures minimal noise and exceptional long-term stability. Its initial accuracy is rated at an impressive **±0.05%**, guaranteeing that the output voltage is within a very tight tolerance of the nominal 3.096V value right from the start.
A key challenge in precision design is maintaining performance across varying temperatures. The REF192GRUZ addresses this with an ultra-low **temperature drift of 3 ppm/°C (max)**. This low drift ensures that the output voltage remains remarkably stable even as the ambient temperature fluctuates, a critical factor in industrial, automotive, and instrumentation environments where thermal conditions are rarely constant. Furthermore, its low **noise performance (4 µVp-p, 0.1 Hz to 10 Hz)** preserves signal integrity, preventing the reference from introducing errors that could be amplified throughout the signal chain.
Beyond its precision, the REF192 is designed for versatility and ease of use. It requires only a minimal **50 µA operating current**, making it suitable for portable, battery-powered instruments where power efficiency is paramount. Its wide input voltage range, from 4.5V to 18V, allows it to be easily integrated into various system power architectures. Housed in a space-saving SOIC-8 package, the device provides a robust solution without demanding significant board area.
The combination of these features makes the REF192GRUZ an indispensable component in applications where measurement accuracy is non-negotiable. It is ideally suited for:
* **Precision Data Acquisition Systems**
* **Industrial Process Control and Automation**
* **Medical Diagnostic and Monitoring Equipment**
* **High-Resolution Digital Multimeters and Calibration Instruments**
* **Portable Test and Measurement Devices**
**ICGOOODFIND:** The REF192GRUZ stands out as a premier solution for designers who cannot compromise on accuracy. Its unparalleled combination of low initial error, minimal temperature drift, and low noise establishes a new benchmark for system precision, ensuring that the entire signal chain performs at its peak from -40°C to +125°C.
