Output is derived from an integrated 2-terminal Zener with a breakdown voltage directly proportional to absolute temperature at 10mV/°K. Calibrated at +25°C, the LM135 has an accuracy of 0.5°C over a wide -55°C to 150°C temperature range. With less than 1Ω dynamic impedance, performance is consistent across a current range of 450μA to 5mA. The device suits use as a general purpose sensor where its small size, low impedance and linear output enables simple circuit integration.

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: VOUTT + VOUTTo x Where: T is the unknown temperature T O is the reference temperature (in °K). Nominally, the output is calibrated at 10mV/°K. T To Application Note: Self-heating can decrease accuracy; LM135 should be operated at low current but sufficient enough to drive the sensor and calibration circuit to the maximum operating temperature. If 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. VOUT 10mV/°K 10kΩ* * Calibrated for 2.982V at 25°C A ll data sheet.com
