... National Semiconductor temperature sensors are always calibrated to the typical non-ideality and series resis- tance of a given processor type. The LM95213 is calibrated for non-ideality factor and series resistance values supporting the MMBT3904 transistor without the requirement for addi- tional trims. When a temperature sensor calibrated for a particular processor type is used with a different processor type, additional errors are introduced ...
