Description
The LM135, LM235, LM335 are precision
temperature sensors which can be easily
calibrated. They operate as a 2-terminal Zener
and the breakdown voltage is directly proportional
to the absolute temperature at 10mV/擄K.
The circuit has a dynamic impedance of less than
1惟 and operates within a range of current from
450碌A to 5mA without alteration of its
characteristics.
Calibrated at +25擄C, the LM135, LM235, and
LM335 have a typical error of less than 1擄C over a
100擄C temperature range. Unlike other sensors,
the LM135, LM235, LM335 have a linear output.
