The LM35D variant provides a 0\u00b0C to +100\u00b0C operating range with \u00b10.5\u00b0C typical accuracy at 25\u00b0C. The device outputs 10mV per degree Celsius, requiring no external calibration. It operates from a single 4V to 30V supply and draws only 60\u00b5A, resulting in very low self-heating of just 0.08\u00b0C in still air. The low 0.1\u03a9 output impedance allows direct interface with ADCs or control circuits without buffering. The TO-92 package is ideal for through-hole mounting in applications where ease of prototyping and thermal contact are priorities.","working_principle":"The LM35DZ\/NOPB uses a pair of transistors operating at different current densities to generate a voltage proportional to absolute temperature (PTAT). Two identical NPN transistors are biased at a 10:1 current ratio, producing a \u0394VBE of (kT\/q)\u00b7ln(10) \u2248 59.16\u00b5V\/\u00b0C. This small PTAT voltage is amplified by an internal precision amplifier to produce the 10mV\/\u00b0C output. The gain is laser-trimmed at wafer level during manufacturing to achieve \u00b10.5\u00b0C accuracy without user calibration. The output buffer provides the low 0.1\u03a9 output impedance, allowing the device to drive capacitive loads and ADC inputs without instability. The 60\u00b5A supply current flows primarily through the bias network and amplifier, and the small die size results in minimal self-heating. For basic temperature sensing, only a single supply and output connection are needed; for negative temperature measurement, a pull-down resistor can be added to the output to sink current below ground.","pin_description":"\n
