Product Overview: LM35CZ Precision Centigrade Temperature Sensor

The LM35CZ is a precision integrated-circuit temperature sensor, produced by Texas Instruments, that can measure temperature with minimal external components. It is specifically designed to provide an output voltage that is linearly proportional to the Centigrade temperature, making it straightforward to interpret the readings.

Key Features

• Linear +10 mV/°C Scale Factor: The LM35CZ provides a simple linear scale of 10 millivolts per degree Celsius, which simplifies interfacing to temperature control circuits and ADCs.
• Wide Temperature Range: This sensor can measure temperatures from -40°C to +110°C, making it suitable for a wide range of applications.
• Low Self-Heating: The LM35CZ exhibits very low self-heating, typically much less than 0.1°C in still air, as it draws only 60 µA from its supply.
• Calibrated Directly in Celsius: There is no need for external calibration to provide typical accuracies of ±¼°C at room temperature and ±¾°C over the full -40°C to +110°C temperature range.
• Low Impedance Output: The low output impedance, linear output, and precise inherent calibration of the LM35CZ make interfacing to readout or control circuitry especially easy.
• Operates from 4V to 30V: The sensor is functional over a wide range of supply voltages, which allows it to be used in various power environments.

Applications

The LM35CZ is versatile and can be used in a multitude of applications, including:

• Environmental controls
