**AD587KRZ-REEL7: A Precision Voltage Reference for Demanding Applications**

In the realm of high-precision electronics, system accuracy is paramount. It is heavily dependent on the stability and reliability of the DC reference voltage that underpins analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and precision measurement equipment. For these demanding applications, the **AD587KRZ-REEL7** stands out as a premier solution, offering exceptional performance where lesser references would falter.

This integrated circuit is a **10.0 V buried Zener-based voltage reference**, a technology renowned for its long-term stability and low noise characteristics. The "KRZ" grade designation signifies its high level of precision, featuring an **initial accuracy of ±0.04% (max)** and an ultra-low temperature drift of **5 ppm/°C (max)**. This ensures that the output voltage remains exceptionally stable across a wide operating temperature range, minimizing errors induced by environmental changes.

A key advantage of the AD587KRZ-REEL7 is its **low noise performance**, typically just 4 µV p-p in the 0.1 Hz to 10 Hz band. This is critical for resolving fine details in sensitive measurement systems, such as medical instrumentation and high-resolution data acquisition systems, where noise can obscure small signals. Furthermore, the device requires only a single external capacitor for noise filtering and stability, simplifying board design and reducing the bill of materials.

The robust design of the AD587 also provides excellent **line regulation (30 µV/V typical)** and **load regulation (0.5 ppm/mA typical)**, making it resilient to fluctuations in supply voltage and output current demands. Housed in an 8-lead SOIC package and supplied in a reel format (-REEL7), it is also optimized for automated assembly processes in high-volume manufacturing.

**ICGOOODFIND**: The AD587KRZ-REEL7 is a benchmark precision voltage reference that delivers top-tier accuracy, outstanding temperature stability, and low noise, making it an indispensable component for designers of high-end industrial, medical, and test and measurement equipment.
