The LM35CH/NOPB is a precision integrated-circuit Temperature Sensor with an output voltage linearly- 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 ±1/4°C at room temperature and ±?°C over a full -55 to 150°C temperature range. The low-output impedance, linear output and precise inherent calibration of the LM35 device makes interfacing to readout or control circuitry especially easy. The device is used with single power supplies or with plus and minus supplies. As the LM35 device draws only 60μA from the supply, it has very low self-heating of less than 0.1°C in still air.
