INTEGRATED CIRCUIT OF TEMPERATURE SENSOR
(analog LM235Z, SGS-Thomson)
Microcircuit IL235Z is precision temperature sensor with calibration
capacity . Microcircuit operates as Zener diode with brake down
voltage being in direct proportion to to absolute temperature (10
mV/OK). Full dynamic resistance of the circuit is less than 1 Оhm at
operation current 450 µА...5 mА. The sensor calibrated at the
temperature 25OС,has typical error less than 1OС in the temperature
range above 100OС. The peculiarity of the circuit IL235Z is the linear
dependence of output voltage versus temperature.

self-heating is proper to any devices of temperature sensors. The circuit should operate at low
operating current but sufficient for controlling the sensor and its calibration circuit at maximum
operating temperature.
When using the sensor in the field with constant thermal resistance, error when self-heating may
be reduced by external calibration. It can be done at the circuit bias when applying temperature-
stabilized current. Thus heating will be proportional to Zener diode voltage. In this case error when
self-heating is proportional to absolute temperature as the error of scaling coefficient.
Typical application circuits.
