The TMP36GT9Z from Analog Devices is a low-voltage, precision centigrade temperature sensor in a 3-lead TO-92 package. It provides an analog output voltage linearly proportional to Celsius temperature with a scale factor of 10 mV\/\u00b0C and a 750 mV offset at 25\u00b0C. Rated from -40\u00b0C to +125\u00b0C with \u00b12\u00b0C typical accuracy, it operates from a single 2.7 V to 5.5 V supply with under 50 \u00b5A quiescent current.<\/p>\n

With a 10 mV\/\u00b0C scale factor and 750 mV output at 25\u00b0C, it allows measurement of negative temperatures on a single supply. The device requires no external calibration and achieves \u00b11\u00b0C accuracy at 25\u00b0C and \u00b12\u00b0C over the -40\u00b0C to +125\u00b0C range. The low quiescent current of less than 50 \u00b5A minimizes self-heating errors to below 0.1\u00b0C in still air. A shutdown function reduces current to below 0.5 \u00b5A for battery-powered applications.","working_principle":"The TMP36GT9Z uses a bandgap reference architecture to generate a voltage output proportional to the absolute temperature. The core sensing element consists of multiple transistors operating at different current densities, producing a differential voltage that is proportional to absolute temperature (PTAT). An on-chip amplifier scales and offsets this PTAT voltage to produce the 10 mV\/\u00b0C output with a 500 mV offset (Vout = 10 mV\/\u00b0C \u00d7 T + 500 mV), allowing the output to read 750 mV at 25\u00b0C and remain above ground for temperatures down to -40\u00b0C. The low output impedance enables direct connection to ADC inputs without buffer amplifiers.","pin_description":"
