The LM135 series are precision, easily-calibrated, integrated circuit temperature Sensors Operating as a 2-terminal zener, the LM135 has a breakdown voltage directly proportional to absolute temperature at +10 mV/?K. With less than 1? dynamic impedance the device operates over a current range of 400 uA to 5 mA with virtually no change in performance. When calibrated at 25?C the LM135 has typically less than 1?C error over a 100?C temperature range. Unlike other Sensors the LM135 has a linear output. Applications for the LM135 include almost any type of temperature sensing over a ?55?C to +150?C temperature range. The low impedance and linear output make interfacing to readout or control circuitry especially easy. The LM135 operates over a ?55?C to +150?C temperature range while the LM235 operates over a ?40?C to +125?C temperature range. The LM335 operates from ?40?C to +100?C. The LM135 LM235 LM335 are available packaged in hermetic TO-46 Transistor packages while the LM335 is also available in plastic TO-92 packages.LM335's datasheet is the same as LM135A
