**REF192ES: A Precision Voltage Reference for Demanding Applications**

In the realm of precision electronics, system performance is fundamentally anchored by the stability and accuracy of its voltage reference. The **REF192ES** stands out as a premier solution, engineered to deliver exceptional performance where it matters most. This article delves into the key attributes that make this component indispensable for high-precision applications.

The core of the REF192ES is its **buried zener diode** topology. This advanced design is renowned for its superior long-term stability and low noise characteristics compared to common bandgap references. It provides a fixed, precise output voltage of **2.500 V, 4.096 V, or 5.000 V**, catering to a wide array of system requirements, particularly in high-resolution data converter systems.

A defining feature of the REF192ES is its **exceptionally low temperature drift**, specified at just **3 ppm/°C (max)**. This ensures that the output voltage remains stable across a wide industrial temperature range, mitigating errors induced by thermal fluctuations. This level of precision is critical for applications such as precision instrumentation, medical equipment, and advanced automotive sensors, where measurement integrity cannot be compromised.

Furthermore, the device boasts **ultra-low noise** performance, typically **4.5 µVp-p** from 0.1 Hz to 10 Hz. This minimizes unwanted signal contamination, which is vital for maintaining the signal-to-noise ratio in sensitive measurement chains. Its low **long-term stability** of **30 ppm/1000 hrs** guarantees that the performance remains consistent over the operational life of the product, reducing the need for frequent calibration.

The REF192ES is designed for ease of integration, requiring only a minimal **0.1 µF bypass capacitor** for stable operation. Its robust design also includes **reverse-voltage protection** and the ability to source and sink up to **10 mA** of load current, enhancing its versatility and resilience in complex circuit environments.

**ICGOODFIND**: The REF192ES establishes itself as a benchmark for precision, offering an optimal blend of ultra-low drift, low noise, and outstanding long-term stability for the most demanding design challenges.
