The LM135, LM235, LM335 are precision temperature sensors which can be easily calibrated. They operate as a 2-terminal Zener and the breakdown voltage is directly proportional to the absolute temperature at 10mV/°K.

The circuit has a dynamic impedance of less than 1Ω and operates within a range of current from 450µA to 5mA without alteration of its characteristics.

Calibrated at +25°C, the LM135, LM235, and LM335 have a typical error of less than 1°C over a 100°C temperature range. Unlike other sensors, the LM135, LM235, LM335 have a linear output.

LM135，LM235，LM335是精密温度传感器可以很容易地校准。他们作为一个2端齐纳击穿电压和是绝对温度成正比的电压/°K.

该电路具有动态小于1Ω阻抗和工作在一个电流范围从450µ一5mA没有特点的变化。

在25°LM135，LM235 C，校准，和LM335有典型的小于1°C在100°C的温度范围内的误差。不像其他的传感器、LM135，LM235，LM335有线性输出。
