LM35DT

The LM35DT is a precision centigrade temperature sensor from Texas Instruments. It is available in a small, hermetically sealed, TO-46 package and is designed for high-precision temperature measurements with a wide temperature range of -55°C to 125°C. The LM35DT is a linearized version of the LM35, offering improved accuracy and stability.

Description:

The LM35DT is a temperature sensor that converts temperature information into a linear voltage output. It has a 10mV/°C scale factor, which means that for every 1°C change in temperature, the output voltage will change by 10mV. The sensor has a low output impedance, making it easy to interface with a wide range of microcontrollers and signal processing circuits.

Features:

1. Wide temperature range: -55°C to 125°C
2. Linearized output: Improved accuracy and stability compared to the standard LM35
3. 10mV/°C scale factor
4. Low output impedance
5. Hermetically sealed TO-46 package
6. Operating voltage range: 4V to 30V
7. Low self-heating: Less than 0.1°C at 10mA output current
8. No calibration required

Applications:

1. Industrial control systems
2. Temperature monitoring in HVAC systems
3. Medical equipment temperature sensing
4. Automotive temperature measurements
5. Appliance temperature control
6. Weather stations and environmental monitoring
7. Laboratory and research equipment temperature sensing
8. Embedded systems for temperature monitoring and control

The LM35DT is a versatile temperature sensor that offers high precision and a wide temperature range, making it suitable for a variety of applications where accurate temperature measurements are required.
