Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For Guaranteed specification and test condition, see the Electrical Characteristics. The guaranteed specficiations apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.
 
Note 2: Continous operation at these temperatures for 10,000 hours may decrease life expectancy of the device.
 

The LM135 is a precision, easily-calibrated, integrated circuit temperature sensor. Operating as a 2-terminal zener, the LM135 has a breakdown voltage directly proportional to absolute temperature at + 10mV/K. With less than 1 Ohm dynamic impedance the LM135 operates over a current range of 400uA to 5 mA with virtually no change in performance. When calibrated at 25C the LM135 has typically less than 1 C error over a 100C temperature range. Unlike other sensors the LM135 has a linear output. The low impedance and linear output make interfacting to readout or control ciruitry especially easy.

This LM135 is tested only at room temperature.
