Precision Temperature Sensors
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/藲K. With less than 1鈩?dy-
namic impedance the device operates over a current range
of 400 碌A to 5 mA with virtually no change in performance.
When calibrated at 25藲C the LM135 has typically less than
1藲C error over a 100藲C temperature range. Unlike other
sensors the LM135 has a linear output.
Applications for the LM135 include almost any type of tem-
perature sensing over a 鈭?5藲C to +150藲C temperature
range. The low impedance and linear output make interfac-
ing to readout or control circuitry especially easy.
The LM135 operates over a 鈭?5藲C to +150藲C temperature
range while the LM235 operates over a 鈭?0藲C to +125藲C
temperature range. The LM335 operates from 鈭?0藲C to
+100藲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.
