The LM35CH is a precision integrated-circuit temperature sensor, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. Manufactured by Texas Instruments, the LM35CH is specifically designed for high-performance, low-cost, and precise temperature measurement. The device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling.

Key Features

• Calibrated Directly in Celsius: The LM35CH provides a linear output that equates to +10mV/°C scale factor without requiring any external calibration, simplifying integration into systems.
• Wide Operating Temperature Range: This sensor operates over a -55°C to +150°C temperature range, making it suitable for a variety of environmental conditions.
• Low Power Consumption: With less than 60 μA current drain, the LM35CH is ideal for battery-powered applications and reduces power consumption in wired systems.
• Low Self-Heating: The device has very low self-heating, less than 0.1°C in still air, which ensures accurate readings and excellent stability.
• High Impedance Output: The high-impedance output of LM35CH makes it less susceptible to noise and easier to interface with readout or control circuitry.

Applications

The LM35CH is versatile for a wide range of applications. It is commonly used in environmental controls, cooling systems, temperature monitoring systems within electronics, HVAC systems, and any application where precise temperature readouts are required.

Package and Quality

Encased in a hermetically sealed TO-CAN package, the LM35CH ensures reliability and stability in various conditions. Texas Instruments is known for its commitment to quality, and the LM35CH is no exception, meeting high standards for performance and durability.

Overall, the LM35CH by Texas Instruments stands out as a go-to solution for designers and engineers looking for an accurate, reliable, and easy-to-use temperature sensor for their projects.
