Description and Introduction

Precision Centigrade Temperature Sensor The LM35CZ is a precision integrated-circuit temperature sensor manufactured by National Semiconductor (now part of Texas Instruments). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Operating Voltage Range:** 4V to 30V  
- **Current Consumption:** < 60 µA (low self-heating)  
- **Temperature Range:** -40°C to +110°C  
- **Accuracy:** ±0.5°C at 25°C (typical)  
- **Output Scale Factor:** 10 mV/°C (linear)  
- **Calibrated Directly in Celsius (°C)**  
- **Low Impedance Output:** 0.1 Ω for 1 mA load  
- **Package:** TO-92 (3-pin)  

### **Descriptions:**  
- The LM35CZ is an analog temperature sensor that provides an output voltage linearly proportional to the Celsius temperature.  
- It does not require external calibration or trimming to maintain accuracy.  
- Suitable for remote applications due to its low self-heating and minimal loading effects.  

### **Features:**  
- **Linear Output:** 10 mV per degree Celsius.  
- **Wide Temperature Range:** -40°C to +110°C.  
- **Low Cost:** Due to wafer-level trimming.  
- **No External Calibration Needed:** Factory-calibrated.  
- **Low Power Consumption:** Draws only 60 µA from the supply.  
- **Stable with Long Wires:** Minimal impedance effects.  

This sensor is commonly used in HVAC systems, battery management, and industrial applications.
