**REF01AZ: The Ultra-Precise, Low-Noise Voltage Reference for Demanding Applications**

In the world of precision electronics, the stability and accuracy of a voltage reference can define the performance ceiling of an entire system. For applications ranging from high-resolution data acquisition and medical instrumentation to precision metrology and advanced communications infrastructure, the **REF01AZ from Analog Devices** stands out as a benchmark of performance and reliability.

This monolithic voltage reference is engineered to provide a **fixed +10V output** with exceptional accuracy, characterized by an initial error of just ±0.2mV (±0.002%). This remarkable precision is maintained over time and varying environmental conditions, thanks to its ultra-low temperature drift of **0.6 ppm/°C, typical**. Such stability ensures that systems perform consistently, eliminating measurement errors that can arise from thermal fluctuations.

A critical differentiator for the REF01AZ is its exceptionally **low noise performance**. In precision systems, noise can obscure minute signals and degrade the overall signal-to-noise ratio (SNR). The REF01AZ addresses this with a noise floor of just **3.5μVp-p (0.1Hz to 10Hz)**, making it an ideal choice for amplifying and sampling the most delicate signals in 16-bit and higher-resolution systems.

Beyond noise and accuracy, the device is designed for robust operation. It features **low long-term stability** (also known as long-term drift), ensuring that its output voltage does not wander significantly over thousands of hours of operation. Its wide operating supply range, from **13.5V to 33V**, and high supply noise rejection ratio make it resilient to power supply variations, a common challenge in real-world environments. The REF01AZ can also source up to 20mA and sink up to 10mA of output current, providing the strength to drive multiple loads directly.

Housed in a sturdy 6-pin TO-99 metal can package, the REF01AZ is built to withstand demanding conditions, making it a preferred component for military, aerospace, and industrial applications where reliability is non-negotiable.

**ICGOODFIND**: The REF01AZ is the definitive solution for designers who cannot compromise on precision. Its unparalleled combination of **ultra-low noise, minimal temperature drift, and high initial accuracy** establishes it as the voltage reference against which others are measured in the most demanding precision analog designs.
