LM135-LM235-LM335 Precision temperature sensors Features ■ Directly calibrated in °K ■ 1°C initial accuracy TO-92 ■ Operates from 450µA to 5mA (Plastic package) ■ Less than 1Ω dynamic impedance Description The LM135, LM235, LM335 are precision SO-8 temperature sensors which can be easily (Plastic micropackage) calibrated. They operate as a 2-terminal Zener and the breakdown voltage is directly proportional to the absolute temperature at 10mV/°K. Pin connections The circuit has a dynamic impedance of less than 1Ω and operates within a range of current from TO-92 450µA to 5mA without alteration of its (Bottom view) characteristics. Calibrated at +25°C, the LM135, LM235, and ADJ v+ v- LM335 have a typical error of less than 1°C over a 100°C temperature range. Unlike other sensors, the LM135, LM235, LM335 have a linear output.

Application information LM135-LM235-LM335 5 Application information There is an easy method of calibrating the device for higher accuracies (see Typical applications). The single point calibration works because the output of the LM135, LM235, LM335 is proportional to the absolute temperature with the extrapolated output of sensor going to 0V at 0°K (-273.15°C). Errors in output voltage versus temperature are only slope. Thus a calibration of the slope at one temperature corrects errors at all temperatures. The circuit output (calibrated or not) is given by the equation: V + VO x T OT TO ------- To 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. As in 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. If the sensor is used in surroundings where the thermal resistance is constant, the errors due to self-heating can be externally calibrated. This is possible if the circuit is biased with a temperature stable current. Heating will then be proportional to Zener voltage and therefore temperature. In this way, the error due to self-heating is proportional to the absolute temperature as scale factor errors. Typical applications Figure 13. Basic temperature sensor Figure 14.
