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 transistor packages while the LM335 is also available in plastic TO-92 packages.

Schematic Diagram

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
