DESCRIPTION

The LM135, LM235, LM335 are precision temperature sensors which can be easily calibrated. They

operate as a 2-terminal Zener and the break down voltage is directly proportional to the absolute temperature at 10mV/oK. The circuit has a dynamic impedance of less than 1Ωand operates within a range of current from 450µA to 5mA without alteration of its characteristics. Calibrated at +25o

C, 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.
