Description and Introduction

Precision Centigrade Temperature Sensor The LM35DH is a precision integrated-circuit temperature sensor manufactured by National Semiconductor Corporation (NSC).  

### **Specifications:**  
- **Temperature Range:** -55°C to +150°C  
- **Output Voltage:** Linear +10.0 mV/°C scale factor  
- **Accuracy:** ±0.5°C (at +25°C)  
- **Operating Voltage:** 4V to 30V  
- **Current Drain:** < 60 μA  
- **Low Self-Heating:** 0.08°C in still air  
- **Non-Linearity:** ±¼°C typical  
- **Package:** TO-46 metal can  

### **Descriptions:**  
- The LM35DH is a high-precision analog temperature sensor that provides an output voltage linearly proportional to the Celsius temperature.  
- It does not require external calibration or trimming.  
- The sensor is designed for industrial, automotive, and consumer applications.  

### **Features:**  
- Calibrated directly in °C (Celsius)  
- Low impedance output (0.1 Ω for 1 mA load)  
- Suitable for remote applications  
- Low-cost due to wafer-level trimming  
- Operates from a single power supply  

This information is based on the manufacturer's datasheet.
