Description and Introduction

?2?C Analog Output Temperature Sensor 3-SOT-23 -20 to 100 The LM45CIM3X-NOPB is a precision integrated-circuit temperature sensor manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Temperature Range:** -40°C to +125°C  
- **Accuracy:** ±2°C (typical at 25°C)  
- **Output Voltage:** 10 mV/°C (linear scale)  
- **Supply Voltage Range:** 4V to 30V  
- **Low Quiescent Current:** 120 µA (typical)  
- **Package:** SOT-23 (3-pin)  
- **Output Impedance:** 0.4 Ω (typical)  
- **Self-Heating Effect:** Low (0.08°C in still air)  

### **Descriptions:**  
- The LM45 is a precision analog output temperature sensor with a linear voltage output proportional to temperature.  
- It does not require external calibration or trimming.  
- Suitable for battery-powered systems due to low power consumption.  

### **Features:**  
- Linear +10 mV/°C scale factor  
- Wide operating voltage range (4V to 30V)  
- Low self-heating (0.08°C in still air)  
- Low impedance output for easy interfacing  
- No external components required  
- Cost-effective and easy to use  

This sensor is commonly used in HVAC systems, industrial controls, and consumer electronics for temperature monitoring.
