Provided is an extension module for independently storing calibration data, including: a first interface, adapted to receive a first external input signal; a second interface, adapted to output the first output signal of the extension module; a signal processing circuit, connected between the first interface and the second interface; and a first memory, the first memory storing first calibration data, and the first calibration data being associated with the extension module. Furthermore, also provided is a component using the above extension module, and a component calibration method. On the one hand, the extension module of an embodiment may share an ADC sampling circuit on a main module, so that the manufacturing cost of the extension module is reduced. On the other hand, an embodiment can facilitate the replacement of different extension modules for the main module without repeated calibration.
