LM135 Datasheet (National Semiconductor) - Precision Temperature Sensors

LM135, 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
