Overview
The LM35DMX/NOPB is a precision integrated-circuit temperature sensor produced by Texas Instruments. This device is part of the LM35 series, which is calibrated directly in Celsius, providing a linear output voltage proportional to the Centigrade temperature. The LM35DMX/NOPB is particularly advantageous as it does not require any external calibration or trimming, offering high accuracy and ease of use. It operates over a wide temperature range and is suitable for various applications due to its low self-heating, low current drain, and low output impedance.
