Description and Introduction

Precision Fahrenheit Temperature Sensors The LM34H is a precision Fahrenheit temperature sensor manufactured by National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Temperature Range:** -50°F to +300°F  
- **Output Scale Factor:** 10 mV/°F  
- **Accuracy:** ±1.0°F (at +77°F)  
- **Supply Voltage Range:** 5V to 30V  
- **Current Drain:** 75 μA (typical)  
- **Nonlinearity:** ±0.5°F (typical)  
- **Output Impedance:** 0.4 Ω (for 1 mA load)  
- **Package:** TO-46 metal can  

### **Descriptions:**
- The LM34H is a linear temperature sensor that provides an output voltage proportional to Fahrenheit temperature.  
- It does not require external calibration or trimming for typical accuracies.  
- The sensor is designed for ease of use in a wide range of temperature measurement applications.  

### **Features:**
- **Direct Fahrenheit Scaling:** Eliminates the need for conversion from Celsius.  
- **Low Self-Heating:** Less than 0.2°F in still air.  
- **Wide Operating Range:** Suitable for industrial and consumer applications.  
- **Linear Output:** 10 mV per degree Fahrenheit.  
- **Low Cost:** Simple interfacing without additional components.  

These details are based on the manufacturer's datasheet for the LM34H.
