The LM335 is a precision temperature sensor which can be easily calibrated. It operates 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 LM335 has a typical error of less than 1°C over a 100°C temperature range. Unlike other sensors, the LM335 has a linear output.
