... Electrical Characteristic for the temperature range of −40°C to +125°C, for example, is specified at ±3°C for the LM56BIM. Note this trip point error specification does not include any error introduced by the tolerance of the actual resistors used, nor any error introduced by power supply vari- ation. If the resistors have a ± ...

... MOUNTING CONSIDERATIONS The majority of the temperature that the LM56 is measuring is the temperature of its leads. Therefore, when the LM56 is placed on a printed circuit board not sensing the tem- perature of the ambient air actually sensing the temper- ature difference of the air and the lands and printed circuit board that the leads are attached to ...
