**AD586KRZ: A Precision Voltage Reference for Demanding Applications**

In the world of precision electronics, system accuracy is only as good as its reference. The **AD586KRZ from Analog Devices** stands as a cornerstone component, providing a stable and precise voltage benchmark critical for high-performance data converters, precision instruments, and measurement systems. This high-precision, 5.0 V buried zener voltage reference is engineered to deliver exceptional performance where it matters most.

The core strength of the AD586KRZ lies in its **exceptional initial accuracy and temperature stability**. With an initial accuracy of ±1 mV (for L, N, S grades) and a low temperature coefficient as tight as 5 ppm/°C, it ensures that the reference point remains unwavering despite fluctuations in ambient temperature. This stability is paramount for maintaining the integrity of measurements and conversions over time and across operating conditions.

Furthermore, the device features **low long-term stability and noise performance**. Its buried zener element, coupled with advanced design and laser wafer trimming (LWT), minimizes drift over thousands of hours of operation. This makes it an ideal choice for systems requiring reliable calibration and minimal maintenance. The low noise characteristic is especially critical in dynamic signal acquisition systems, preventing the reference from introducing errors into sensitive measurements.

Housed in a compact 8-pin SOIC package, the AD586KRZ is designed for versatility. It requires a minimal operating current and can source or sink up to 10 mA of output current, allowing it to drive multiple loads directly. Its **robust design and high output current capability** make it suitable for a wide array of applications, from industrial process control and automated test equipment (ATE) to precision digital multimeters and medical instrumentation.

**ICGOOODFIND:** The AD586KRZ is a quintessential precision voltage reference that masterfully balances high initial accuracy, outstanding temperature stability, and robust performance. It is an indispensable component for design engineers who refuse to compromise on system precision and long-term reliability in their most demanding applications.
