series introduction
# Introduction to the AZ431AN - ATRE1 Product Series
## 1. Overview
The AZ431AN - ATRE1 is a precision adjustable shunt voltage reference series that plays a crucial role in a wide range of electronic circuits. These devices are designed to provide a stable and accurate reference voltage, which is essential for the proper functioning of various analog and digital systems. With their high precision, low temperature coefficient, and excellent line and load regulation characteristics, the AZ431AN - ATRE1 series is a popular choice among engineers and designers.
## 2. Key Features
### 2.1 Precision Voltage Reference
- The AZ431AN - ATRE1 offers a highly accurate reference voltage. It can be adjusted to a specific output voltage within a certain range, typically with a tolerance as low as ±0.5%. This high precision ensures that the voltage reference remains stable and consistent, even in the presence of variations in input voltage, temperature, and load conditions.
- The reference voltage can be set using an external resistor network, allowing for flexibility in different applications.
### 2.2 Low Temperature Coefficient
- Temperature changes can significantly affect the performance of electronic components. The AZ431AN - ATRE1 series has a low temperature coefficient, which means that the reference voltage changes minimally with temperature variations. This characteristic is crucial in applications where the operating environment may experience temperature fluctuations, such as industrial control systems and automotive electronics.
### 2.3 Excellent Line and Load Regulation
- **Line Regulation**: It can maintain a stable output voltage even when the input voltage changes. This is important in power supply circuits where the input voltage may vary due to factors such as power grid fluctuations or battery discharge. The AZ431AN - ATRE1 can quickly adjust to these changes and keep the reference voltage constant.
- **Load Regulation**: When the load connected to the device changes, the AZ431AN - ATRE1 can still provide a stable output voltage. This ensures that the performance of the overall circuit is not affected by variations in the load current.
### 2.4 Wide Operating Temperature Range
The series is designed to operate over a wide temperature range, typically from -40°C to +125°C. This makes it suitable for use in harsh environments, such as automotive under - hood applications, aerospace systems, and industrial control panels.
### 2.5 Low Output Noise
The AZ431AN - ATRE1 generates low output noise, which is essential in applications where a clean and stable reference voltage is required. Low noise levels help to improve the signal - to - noise ratio in analog circuits, resulting in better overall performance.
## 3. Package and Pin Configuration
The AZ431AN - ATRE1 is available in a small - outline package, which is suitable for surface - mount technology (SMT) applications. The package is compact, allowing for high - density circuit board designs.
The device typically has three pins:
- **Anode (A)**: This is the negative terminal of the device. It is usually connected to the ground or a low - voltage reference point in the circuit.
- **Cathode (K)**: The positive terminal. It is connected to the power supply or a higher - voltage point in the circuit.
- **Reference (R)**: This pin is used to set the reference voltage. By connecting external resistors between the reference pin, anode, and cathode, the desired output voltage can be achieved.
## 4. Applications
### 4.1 Power Supply Circuits
- In linear and switching power supplies, the AZ431AN - ATRE1 can be used as a voltage reference for voltage regulation. It helps to maintain a stable output voltage, improving the efficiency and reliability of the power supply. For
