The LM135, LM235, LM335 are precision tempera-
ture sensors which can be easily calibrated. They
operate as a 2-terminal Zener and the breakdown
voltage is directly proportional to the absolute tem-
perature at 10mV/oK. The circuit has a dynamic im-
pedance of less than 1Ω and operates within a
range of current from 450µA to 5mA without altera-
tion of its characteristics. Calibrated at +25oC, the
LM135, LM235, LM335 have a typical error of less
than 1oC over a 100oC temperature range. Unlike
other sensors, the LM135, LM235, LM335 have a
linear output.
