Description and Introduction

Precision Micropower Shunt Voltage Reference The LM4040AIZ-2.5 is a precision voltage reference manufactured by NS (National Semiconductor). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 2.5V  
- **Tolerance:** ±0.1% (A-grade)  
- **Temperature Coefficient:** 100 ppm/°C (max)  
- **Operating Current Range:** 60 µA to 15 mA  
- **Output Voltage Noise:** 35 µVp-p (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TO-92 (3-pin)  
- **Long-Term Stability:** 20 ppm/1000 hrs (typical)  

### **Descriptions:**
- The LM4040AIZ-2.5 is a shunt-mode precision voltage reference.  
- It provides a fixed 2.5V output with high accuracy and low noise.  
- Designed for applications requiring stable voltage references, such as ADCs, DACs, and power supplies.  
- Reverse breakdown voltage is fixed with tight tolerances.  

### **Features:**
- **High Accuracy:** ±0.1% initial tolerance (A-grade).  
- **Low Noise:** 35 µVp-p typical.  
- **Wide Operating Current:** 60 µA to 15 mA.  
- **Low Temperature Drift:** Ensures stable performance over temperature variations.  
- **No External Capacitor Required:** Stable without additional components.  
- **Reverse Breakdown Operation:** Operates in shunt (two-terminal) mode.  

This device is suitable for precision voltage reference applications in industrial, automotive, and instrumentation systems.
