The LM35 thus has an advantage over linear temperature sensors calibrated in ° Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient centigrade scaling.
The sensor does not require any external calibration or trimming to provide typical accuracies of ±0,25 °C at room temperature and ±0,75 °C over a full 0...100 °C temperature range. Low cost is assured by trimming
and calibration at the wafer level. The LM35DZ´s low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy. It can be used with single
power supplies, or with plus and minus supplies. As it draws only 60 μA from its supply, it has very low self-heating, less than 0.1 °C in still air. The LM35DZ is rated to operate over a 0...100 °C temperature range.
