LM335 Precision Temperature Sensors

The LM135 series are precision, easily-calibrated, integrated circuit temperature sensors. Operating as a 2-terminal zener, the LM135 has a breakdown voltage directly proportional to absolute temperature at +10 mV/˚K. With less than 1Ω dynamic impedance the device operates over a current range of 40.
