LM135/LM235/LM335, LM135A/LM235A/LM335A

The LM135 series are precision, easily-calibrated, integratedcircuit temperature sensors. Operating as a 2-terminal zener,the LM135 has a breakdown voltage directly proportional toabsolute temperature at +10 mV/°K. With less than 1W dynamicimpedance the device operates over a current rangeof 400 μA to 5 mA with virtually no change in performance.When calibrated at 25°C the LM135 has typically less than1°C error over a 100°C temperature range. Unlike other sensorsthe LM135 has a linear output....
