Description and Introduction

Precision Centigrade Temperature Sensor The LM-35 is a precision integrated-circuit temperature sensor manufactured by **Allegro MicroSystems**. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Temperature Range:** -55°C to +150°C  
- **Output Voltage:** Linear +10.0 mV/°C  
- **Accuracy:** ±0.5°C (at +25°C)  
- **Supply Voltage:** 4V to 30V  
- **Current Drain:** <60 µA  
- **Low Self-Heating:** 0.08°C in still air  
- **Non-Linearity:** ±¼°C (typical)  
- **Output Impedance:** 0.1 Ω for 1 mA load  

### **Descriptions:**  
- The LM-35 is a **precision analog temperature sensor** that provides an output voltage linearly proportional to the Celsius temperature.  
- It is **calibrated directly in °C**, eliminating the need for external calibration.  
- Operates over a **wide temperature range** with low power consumption.  
- Suitable for **remote applications** due to its minimal self-heating.  

### **Features:**  
- **No external calibration or trimming required**  
- **Low cost due to wafer-level trimming**  
- **Suitable for remote applications**  
- **Linear output eliminates the need for complex signal conditioning**  
- **Low impedance output ensures easy interfacing with control circuits**  

This information is sourced from Allegro MicroSystems' official documentation on the LM-35 temperature sensor.
