The LM335 is a widely used and precise integrated circuit (IC) categorized as a temperature sensor. It converts temperature directly into a proportional voltage output, making it ideal for various temperature measurement and control applications. Here's a breakdown of its key characteristics:
Type: Precision Temperature Sensor
Function: Measures temperature and outputs a voltage directly proportional to the absolute temperature (in Kelvin).
Key Features:
Calibrated Output: Calibrated in degrees Kelvin (K) with a typical scale factor of 10 mV/K. This means the output voltage increases by 10 millivolts for every degree Kelvin rise in temperature.
Wide Temperature Range: Functional operating range typically spans from -55°C to +150°C (check datasheet for specific range).
High Accuracy: Offers good initial accuracy (around ±1°C) at room temperature (25°C).
Linear Output: The output voltage has a linear relationship with temperature, simplifying calculations and interpretations.
Low Cost: An affordable solution for temperature measurement applications.
Benefits:
Simple and Reliable Temperature Measurement: Provides a straightforward way to convert temperature into a voltage signal for easy processing by electronic circuits.
Linear Output: Simplifies conversion of voltage readings to temperature values.
Wide Operating Range: Suitable for various temperature measurement applications.
Low Cost: A cost-effective choice for temperature sensing.
