Description
These are precision temperature sensors which can be easily calibrated and 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 1Ohm and operates within a range of current from 450uA to 5mA without alteration of its characteristics. The LM335Z is calibrated at +25C and has a typical error of less than 1C over a 100C temperature range.
