... The Integrated LM57 Circuit National Semiconductor developed the LM57 integrated cir- cuit to provide a complete temperature sensor and over- temperature alarm solution in one component. It integrates all the features of the discrete circuit shown in Figure 1, plus it includes additional features – ...
