... where T is the unknown temperature and To is the reference temperature (in °K). Nominally, the output is calibrated at 10mV/°K. Precautions should be taken to ensure good sensing accuracy the case of all temperatures sensors, self-heating can decrease accuracy. The LM135, LM235, and LM335 should operate with a low current but sufficient to drive the sensor and its calibration circuit to their maximum operating temperature ...
