The NTE7225 is a precision temperature sensor in a TO92 type package which can be easily calibrated. This device operates as a 2−Lead 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 NTE7225 has a typical error of less than 1°C over a 100°C temperature range. Unlike other sensors, the NTE7225 has a linear ouput.
