Unlike thermistors or RTDs that require external signal conditioning, the LM35 provides a direct voltage output readable by any ADC without calibration or trimming. At 25\u00b0C, it achieves \u00b10.5\u00b0C typical accuracy, and the linear output eliminates lookup tables or polynomial calculations. The TO-220 package allows heat sink attachment for measuring surface or ambient temperature, and the 60 \u00b5A supply current ensures self-heating is below 0.1\u00b0C in still air. The DT suffix indicates the TO-220 package rated for the full -55\u00b0C to +150\u00b0C range.","working_principle":"The LM35DT\/NOPB uses a bandgap-based temperature sensing circuit where the difference in base-emitter voltage (VBE) between two bipolar transistors operating at different current densities is proportional to absolute temperature (PTAT). This PTAT voltage is amplified and offset so that 0\u00b0C corresponds to 0V output, with a precisely trimmed gain of 10 mV\/\u00b0C. The internal reference and trimming are performed at the factory using laser trimming of thin-film resistors, ensuring \u00b10.5\u00b0C accuracy at 25\u00b0C without any user calibration. The low 60 \u00b5A supply current minimizes Joule heating (P = V x I = 5V x 60\u00b5A = 0.3 mW), keeping self-heating errors below 0.1\u00b0C in still air. The low output impedance (0.1 Ohm) allows direct connection to ADC inputs without buffer amplifiers. For negative temperature measurement, a pull-down resistor to a negative supply enables the output to go below ground.","pin_description":"
