Description and Introduction

Precision Fahrenheit Temperature Sensor The LM34DZ is a precision Fahrenheit temperature sensor manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:  

### **Specifications:**  
- **Temperature Range:** -50°F to +300°F (-45.6°C to +148.9°C)  
- **Output Voltage:** 10 mV/°F (linear scale)  
- **Accuracy:** ±0.5°F at +77°F (±0.3°C at +25°C)  
- **Supply Voltage:** 5V to 30V  
- **Current Drain:** <90 µA  
- **Low Self-Heating:** 0.18°F in still air  
- **Package:** TO-92 (3-pin plastic package)  
- **Calibrated Directly in Fahrenheit**  

### **Descriptions:**  
- The LM34DZ is an analog temperature sensor that provides a voltage output linearly proportional to the Fahrenheit temperature.  
- It does not require external calibration or trimming for typical accuracies.  
- Designed for ease of use in temperature measurement applications.  

### **Features:**  
- **Linear Output:** 10 mV per °F scale factor  
- **Wide Temperature Range:** Suitable for industrial and consumer applications  
- **Low Power Consumption:** Operates on minimal current  
- **No External Components Required:** Directly interfaces with readout or control circuitry  
- **High Accuracy:** Maintains precision over its operating range  
- **Low Self-Heating:** Minimizes measurement errors  

This sensor is commonly used in HVAC systems, industrial controls, and automotive applications for accurate temperature monitoring.
