Description

The LM35 series are precision integrated-circuit temperature devices with an output voltage lineary-proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The LM35 device does not require any external calibration or trimming to provide typical accuracies of ‡¼°C at room temperature and +¾°C over a full -55°C to 150°C temperature range. Lower cost is assured by trimming and calibration at the wafer level.
