General Description
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 1Ω dynamic impedance
the device operates over a current range of 400 μA 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.
