**AD589SH: The High-Precision Voltage Reference Standard**

In the realm of precision electronics, the stability and accuracy of a voltage reference are paramount. The **AD589SH** stands as a benchmark in this critical category, providing designers with a robust and highly reliable solution for applications where precision cannot be compromised. This monolithic, two-terminal, **low-noise voltage reference** delivers a fixed 1.23V output, a value strategically chosen to optimize its performance across a wide range of temperatures.

The core strength of the AD589SH lies in its exceptional **temperature stability**, boasting a typical temperature coefficient of just **10 ppm/°C**. This remarkable characteristic ensures that the output voltage remains extraordinarily consistent even as ambient conditions fluctuate, a non-negotiable requirement for precision instrumentation, data acquisition systems, and high-resolution analog-to-digital converters (ADCs). Its two-terminal "zener" mode operation allows it to be used almost as simply as a traditional zener diode but with vastly superior performance. It can be easily configured with a single current-set resistor to operate over a wide current range of 50 µA to 5 mA, offering tremendous flexibility in various circuit designs.

Furthermore, the device exhibits low dynamic impedance and minimal long-term drift, enhancing its reliability over the lifetime of a product. Its ability to **operate with exceptionally low quiescent current** makes it equally suitable for portable and battery-powered equipment where power efficiency is crucial. Whether it's serving as the foundational reference for a digital voltmeter, a precision regulator, or a calibration standard, the AD589SH provides the confidence that measurement and control systems are built upon a solid and unwavering foundation.

ICGOOODFIND: The AD589SH establishes itself as an industry-standard, two-terminal precision voltage reference, renowned for its **10 ppm/°C temperature stability**, simple application, and reliable performance in critical measurement systems.
