# REF1004I - 2 Product Series Introduction

## 1. Overview
The REF1004I - 2 product series represents a cutting - edge solution in the field of precision voltage references. These references are engineered to provide highly accurate and stable voltage outputs, making them an essential component in a wide range of electronic systems where precision is of utmost importance. Whether it's in test and measurement equipment, data acquisition systems, or high - performance analog circuits, the REF1004I - 2 series offers reliable and consistent performance.

## 2. Key Features

### 2.1 High Precision
- **Low Initial Error**: The REF1004I - 2 series boasts an extremely low initial output voltage error. This means that right out of the box, the voltage reference provides an output that is very close to its specified nominal value. For example, if the nominal output voltage is set at a certain value, the actual output will deviate only minimally from this value, ensuring accurate voltage levels for downstream circuits.
- **Tight Temperature Coefficient**: Temperature can have a significant impact on the performance of voltage references. However, the REF1004I - 2 series is designed with a tight temperature coefficient. This means that the output voltage remains relatively stable over a wide temperature range. Whether the device is operating in a cold environment or a high - temperature industrial setting, the voltage output will not vary significantly, maintaining the accuracy of the overall system.

### 2.2 Excellent Line and Load Regulation
- **Line Regulation**: It has outstanding line regulation capabilities. This implies that changes in the input voltage have a minimal effect on the output voltage. Even when there are fluctuations in the power supply voltage, the REF1004I - 2 can maintain a stable output voltage, providing a reliable reference for other components in the circuit.
- **Load Regulation**: The series also offers excellent load regulation. As the load connected to the voltage reference changes, the output voltage remains stable. This is crucial in applications where the load may vary during normal operation, such as in battery - powered devices or systems with variable - impedance loads.

### 2.3 Low Noise
Noise in a voltage reference can introduce errors in sensitive analog circuits. The REF1004I - 2 series is designed to have low output noise. This low - noise characteristic ensures that the voltage reference provides a clean and stable signal, which is essential for applications such as audio processing, sensor interfaces, and high - resolution analog - to - digital converters.

### 2.4 Wide Operating Voltage Range
The REF1004I - 2 can operate over a wide range of input voltages. This flexibility allows it to be used in various power supply configurations, making it suitable for different types of electronic systems. Whether it's a low - voltage battery - powered device or a high - voltage industrial application, the REF1004I - 2 can adapt to the available power supply.
