    摘要: An analog switch and a battery pack using the same are provided. The analog switch can compensate for temperature dependence of voltages measured from a battery cell before applying the measured voltages to an analog-to-digital (A/D) converter. In an embodiment of the analog switch, a first diode is coupled in a backward direction from a flying capacitor, which is coupled to the A/D converter, to correspond to a second diode packaged therewith as a single set. The first diode is positioned in a battery cell voltage input path to store battery cell voltage values in the flying capacitor, while the second diode suppresses a temperature-related difference caused by the first diode to voltages measured from the battery cell.
