Description and Introduction

SOT-23 Single-Supply Centigrade Temperature Sensor The LM50 is a precision integrated-circuit temperature sensor manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer Specifications:**  
- **Supply Voltage Range:** 4.5V to 10V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Voltage:** 10mV/°C (linear slope)  
- **Accuracy:** ±2°C (at 25°C)  
- **Quiescent Current:** 120µA (typical)  
- **Output Impedance:** 80Ω (typical)  
- **Package Options:** TO-92, SOT-23  

### **Descriptions:**  
- The LM50 is an analog temperature sensor that provides a voltage output linearly proportional to the Celsius temperature.  
- It is calibrated to output 500mV at 0°C and increases by 10mV per degree Celsius.  
- The device does not require external calibration and is designed for low-cost applications.  

### **Features:**  
- Linear +10mV/°C scale factor  
- Operates from a single power supply (4.5V to 10V)  
- Low self-heating (0.08°C in still air)  
- Wide temperature range (-40°C to +125°C)  
- Low quiescent current (120µA typical)  
- Directly calibrated in Celsius (°C)  
- Suitable for remote applications due to low output impedance  

These details are sourced from Texas Instruments' official documentation on the LM50 temperature sensor.
