Features
The LM135AH ensures high accuracy with a typical calibration error of ±1°C, improving measurement reliability. It features a low output impedance, making it easy to interface with other circuitry without the need for buffering. The device is also known for its excellent long-term stability and low self-heating, which minimizes temperature measurement errors due to the sensor's own power dissipation.
Additionally, the LM135AH is housed in a TO-46 metal can package, which provides robust protection and enhances thermal conductivity. This sensor is often used in applications such as temperature monitoring systems, HVAC controls, and electronic equipment temperature management. Its simplicity, reliability, and precision make it a popular choice for various thermal sensing applications.
Pinout
1. Pin 1 (V+): Supply voltage input. This is where you connect the power supply to the sensor.
2. Pin 2 (Output): Temperature sensor output. The voltage at this pin is proportional to the temperature in Kelvin, typically 10 mV/K.
3. Pin 3 (GND): Ground. This is the reference point for the power supply and output voltage.
The LM135AH is designed to provide a linear output voltage that corresponds to the ambient temperature, making it easy to interface with analog or digital systems to monitor temperature changes. It operates over a wide temperature range and is suitable for various precision temperature measurement applications.
