The LM35CZ is a precision centigrade temperature sensor with analogue output in 3 pin TO-92 package. The output voltage is linearly proportional to centigrade temperature. The LM35CZ has an advantage over linear temperature sensors calibrated in Kelvin. The user is not required to subtract large constant voltage from output to obtain convenient centigrade scaling. This 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°C to 150°C temperature range. Lower cost is assured by trimming and calibration at wafer level. The low output impedance, linear output and precise inherent calibration of LM35 makes interfacing to readout or control circuitry easy. The device is used with single power supplies or with plus and minus supplies.
