series introduction
# REF5025AID Product Series Introduction
## 1. Overview
The REF5025AID is a highly reliable and precision voltage reference product series designed to meet the demanding requirements of various electronic applications. Voltage references are crucial components in electronic circuits as they provide a stable and accurate voltage level that other parts of the circuit can rely on for proper operation. The REF5025AID series stands out for its exceptional performance in terms of accuracy, temperature stability, and low noise, making it an ideal choice for a wide range of industries and applications.
## 2. Key Features
### 2.1 High Precision
- The REF5025AID offers an initial output voltage accuracy of up to ±0.05%. This high level of precision ensures that the voltage provided by the reference is extremely close to the nominal value of 2.5V. In applications where accurate voltage measurements or control are required, such as in test and measurement equipment, this precision is essential for obtaining reliable and repeatable results.
- The low temperature coefficient of the output voltage further enhances the precision over a wide temperature range. With a temperature coefficient as low as 10 ppm/°C, the output voltage remains stable even when the ambient temperature changes, minimizing errors in the overall system performance.
### 2.2 Low Noise
- Noise can be a significant issue in sensitive electronic circuits, as it can introduce errors and degrade the performance of the system. The REF5025AID series features low output noise, typically less than 10 μVp - p (peak - to - peak) over a frequency range of 0.1 Hz to 10 Hz. This low noise characteristic makes it suitable for applications such as audio amplifiers, data acquisition systems, and medical devices, where a clean and stable voltage reference is required.
### 2.3 Wide Supply Voltage Range
- The REF5025AID can operate over a wide supply voltage range, typically from 2.7V to 18V. This flexibility allows it to be used in a variety of power supply configurations, making it compatible with different types of electronic systems. Whether the application uses a low - voltage battery - powered circuit or a higher - voltage power supply, the REF5025AID can provide a stable 2.5V reference voltage.
### 2.4 Low Power Consumption
- In today's energy - conscious world, low power consumption is a highly desirable feature. The REF5025AID series consumes very low quiescent current, typically less than 100 μA. This low power consumption not only helps to extend the battery life in portable devices but also reduces the overall power dissipation in the system, which can lead to improved reliability and reduced cooling requirements.
### 2.5 Small Package Size
- The REF5025AID is available in a small and compact package, such as the SOT - 23 package. The small package size makes it suitable for space - constrained applications, such as printed circuit boards (PCBs) in mobile devices, wearables, and other miniaturized electronic products. It allows for easy integration into the circuit design without taking up too much board space.
## 3. Applications
### 3.1 Test and Measurement Equipment
- In test and measurement instruments such as multimeters, oscilloscopes, and data loggers, accurate voltage references are essential for making precise measurements. The high precision and low noise characteristics of the REF5025AID ensure that the measurement results are reliable and accurate. It can be used as a reference voltage for analog - to - digital converters (ADCs) and digital - to - analog converters (DACs) in these instruments, providing a stable voltage level for accurate signal conversion.
