Here are taken from the application note:
The LM34 has an output of 10 mV/˚F with a typical nonlinearity of only ± 0.35˚F over a −50 to +300˚F temperature range, and is accurate to within ± 0.4˚F typically at room temperature (77˚F). The LM34’s low output impedance and linear output characteristic make interfacing with readout or control circuitry easy. An inherent strength of the LM34 over other currently available temperature sensors is that it is not as susceptible to large errors in its output from low level leakage currents. For instance, many monolithic temperature sensors have an output of only 1 µA/˚K. This leads to a 1˚K error for only 1 µ-Ampere of leakage current. On the other hand, the LM34 may be operated as a current mode device providing 20 µA/˚F of output current.
Additionally, the application note contains discussion such as reasonably expected, thermometer, supply, leakage currents, output, range, temperature sensor, constant, frequency, applications, state circuits, current densities, and wire remote temperature.
