LM135-LM235-LM335
Precision temperature sensors
Features
■ Directly calibrated in °K
■ 1°C initial accuracy
■ Operates from 450µA to 5mA
■ Less than 1Ω dynamic impedance
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/°K.
The circuit has a dynamic impedance of less than
1Ω and operates within a range of current from
450µA to 5mA without alteration of its
characteristics.
Calibrated at +25°C, the LM135, LM235, and
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.
