概述

Description

The LM35CZ is a precision integrated-circuit temperature sensor that produces a linear voltage output directly proportional to the Celsius temperature. Designed by Texas Instruments, it is part of the LM35 series and is renowned for its accuracy and ease of use in various temperature sensing applications. The LM35CZ operates over a range of -40°C to +110°C and provides a typical accuracy of ±0.5°C at 25°C. It generates an output voltage that is 10mV per degree Celsius, making it straightforward to interpret the readings without additional calibration.
The sensor is highly suitable for applications that require accurate temperature measurements without complex interfacing. It features low self-heating, less than 0.1°C in still air, which ensures that the sensor does not significantly affect the temperature of the environment it is measuring. The LM35CZ can be powered from a wide range of supply voltages, typically from 4V to 30V, adding to its versatility. It is packaged in a TO-92 format, making it easy to integrate into a variety of electronic projects and circuits. Common applications include HVAC systems, automotive temperature monitoring, and consumer electronics.

Features

The LM35CZ is a precision integrated-circuit temperature sensor, widely used for measuring temperature with a high degree of accuracy. Key features include:
1. Calibrated Output: It provides an output voltage linearly proportional to the Celsius temperature, facilitating easy temperature readings without requiring external calibration.
2. Accuracy: Offers a high level of accuracy, typically within ±0.5°C at room temperature and ±1°C over a full range from -40°C to 110°C.
3. Linear Output: The sensor outputs a linear scale of 10 mV/°C, making it straightforward to convert voltage readings into temperature values.
4. Low Self-Heating: With low self-heating, it minimizes temperature measurement errors caused by the sensor itself, typically less than 0.1°C in still air.
5. Wide Operating Voltage: Can operate from 4V to 30V, adding flexibility to its use in various applications.
6. Low Power Consumption: Consumes only about 60 µA, making it suitable for battery-powered devices.
7. Small Package Size: Available in a TO-92 package, the LM35CZ is compact and easy to integrate into various designs.
These features make the LM35CZ ideal for numerous applications, including consumer electronics, environmental monitoring, and industrial systems.

Package

The LM35CZ is a temperature sensor that typically comes in a TO-92 package. This package type is a small, three-lead, plastic transistor outline, commonly used for various electronic components.

Pinout

The LM35CZ is a temperature sensor with three pins. It provides a linear output voltage proportional to the temperature in degrees Celsius.
1. Pin 1 (V\+): This is the power supply pin. It requires a DC voltage typically between 4V and 30V for operation.
2. Pin 2 (Vout): This is the output pin. The LM35CZ outputs an analog voltage that corresponds to the temperature, with a scaling factor of 10 mV/°C. For example, at 25°C, the output voltage would be 250 mV.
3. Pin 3 (GND): This is the ground pin and should be connected to the system ground.
The LM35CZ is known for its accuracy and ease of use, as it doesn’t require any external calibration. It is suitable for a variety of applications where temperature monitoring and control are needed.
