LM235 LM235Z Temperature Sensor

Directly calibrated in °K
1°C initial accuracy
Operates from 450μA to 5mA
Less than 1Ω dynamic impedance

The LM235 Is precision temperature sensor which can be easily calibrated. It 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.
