**REF195GSZ-REEL7: A Precision 2V Voltage Reference for Demanding Applications**

In the realm of high-precision electronics, system performance is often gated by the accuracy and stability of its foundational components. At the heart of many data acquisition systems, precision analog-to-digital converters (ADCs), and digital-to-analog converters (DACs) lies a critical element: the voltage reference. The **REF195GSZ-REEL7** from Analog Devices stands out as a premier solution, engineered to deliver exceptional accuracy and reliability for the most demanding applications.

This voltage reference IC generates a fixed, precise **2.5V output voltage** with an initial accuracy of ±0.06%. This remarkable precision ensures that subsequent measurements or signal generations are based on a rock-solid foundation, minimizing errors and maximizing system integrity. What truly sets the REF195 apart is its ultra-low **temperature drift of 5ppm/°C** (max). This specification is paramount for applications operating over a wide temperature range, as it guarantees that the output voltage remains stable and predictable despite fluctuations in ambient temperature, a common challenge in industrial, automotive, and medical environments.

Beyond mere accuracy, the REF195GSZ-REEL7 is designed for robustness. It features an extremely low **long-term stability of 50ppm/1000 hrs**, which translates to consistent performance over the lifetime of the product. Furthermore, it can source up to **30mA of output current** and sink up to 15mA, a significant capability that allows it to power external circuitry directly, such as the reference input of multiple ADCs, thereby simplifying system design and reducing component count. Its low dropout voltage enables operation with a wide input voltage range, enhancing its versatility.

The device is offered in the space-saving 8-lead SOIC package and is available in a tape-and-reel (REEL7) format, making it perfectly suited for automated assembly processes in high-volume manufacturing. Key applications include:

* Precision Data Acquisition Systems

* High-Resolution ADCs and DACs

* Industrial and Process Control Systems

* Medical Instrumentation

* Automotive Sensor Interfaces

* Portable Test and Measurement Equipment

**ICGOOFind**

The REF195GSZ-REEL7 is a high-performance voltage reference that provides a critical combination of high initial accuracy, excellent temperature stability, and robust output current capability. It is an ideal choice for designers who cannot compromise on precision and reliability in their advanced electronic systems.
