LM35AH/NOPB is a temperature sensor with both analog and digital output, known for its accuracy, wide supply range, low power consumption, and high stability. The device is available in 5-pin miniature thermistor package. The temperature sensor measures temperatures ranging from -55°C to 150°C.

Application Field

The LM35AH/NOPB temperature sensor is widely used in many different application fields, from industrial to automotive and aerospace. In the industrial sector, it is often used for level and pressure monitoring, temperature control, or process monitoring and control. In automotive applications, the sensor is mostly used for vehicle comfort and engine control, such as cabin temperature control and engine temperature monitoring. Finally, in the aerospace sector, it is used in aircraft avionics as well as communication systems, and temperature control systems.

Working Principle

The LM35AH/NOPB temperature sensor measures the temperature of the environment using an on-chip thermistor. The thermistor changes its resistance when exposed to different temperature levels. The resistance of the thermistor is then converted into a voltage that is proportional to the temperature of the environment. The voltage is then output through the device\'s analog and digital output terminals so it can be read by an external device.

The analog output of the device can output a range of voltages from 0V to 5V. The temperature can be read from the voltage with a resolution of 10mV/°C. The on-chip signal conditioning also ensures stability of the output voltage over time. In addition, the device has a digital interface, which allows for a bi-directional communication between the device and an external host controller. This allows the sensor to be remotely controlled and monitored.

The LM35AH/NOPB temperature sensor is a simple and reliable solution for temperature sensing and monitoring. Its accuracy, wide supply range, low power consumption, and high stability makes it a good choice for many different applications. Additionally, with its analog and digital outputs, it offers flexibility for both simple and complex applications.
