**The AD587KRZ-REEL: A Precision Voltage Reference for Demanding Applications**

In the realm of high-precision electronics, the stability and accuracy of a voltage reference are paramount. They serve as the foundational anchor for analog-to-digital and digital-to-analog converters, data acquisition systems, and precision instruments, directly determining the overall system performance. Among the elite components in this category, the **AD587KRZ-REEL** from Analog Devices stands out as a premier solution for the most demanding applications.

The AD587KRZ-REEL is a monolithic, laser-trimmed, 10.0V precision voltage reference. Its core value lies in its **exceptional initial accuracy and long-term stability**. With an initial accuracy of ±0.01% (or ±1mV) and a low temperature coefficient of 5ppm/°C maximum, this device ensures that the output voltage remains consistently reliable even as environmental conditions fluctuate. This level of precision is critical in applications where minute errors can lead to significant deviations in measurement or control, such as in precision calibrators, medical imaging equipment, and advanced scientific instruments.

A key feature that distinguishes the AD587KRZ-REEL is its **low noise performance**. Voltage references can introduce noise into a system, which degrades signal integrity, particularly in high-resolution systems. The AD587 addresses this with a low noise spectral density of 4µV p-p from 0.1Hz to 10Hz, ensuring a clean and stable reference that does not compromise the performance of downstream components.

Furthermore, the device is designed for ease of integration and robustness. It requires no external components for basic operation, simplifying board design and reducing the bill of materials. Its **robust output stage can source or sink up to 5mA of current**, enhancing its versatility in various circuit configurations. The part is offered in an 8-lead SOIC package, which is suitable for a wide range of commercial and industrial environments. The "-REEL" suffix indicates it is supplied on a tape-and-reel, making it ideal for automated high-volume assembly lines.

Applications for the AD587KRZ-REEL are extensive. It is perfectly suited for:

* **High-Resolution Data Acquisition Systems (16-Bit and Above):** Providing the stable baseline required for accurate signal conversion.

* **Precision Digital Multimeters and Calibration Equipment:** Where measurement integrity is non-negotiable.

* **Medical and Analytical Instrumentation:** Demanding high accuracy and reliability for critical diagnostics and analysis.

* **Automatic Test Equipment (ATE) and Industrial Control Systems:** Where long-term stability minimizes the need for frequent recalibration.

**ICGOODFIND:** The AD587KRZ-REEL is more than just a voltage reference; it is a **benchmark of precision and reliability**. Its combination of ultra-low noise, high initial accuracy, and excellent temperature stability makes it an indispensable component for engineers designing systems where performance cannot be compromised. For applications that demand the highest level of precision, the AD587KRZ-REEL provides a trusted and proven solution.
