Before supplying power to the chip, the power must be filtered through a capacitor. The
power supply route is: the positive end of the battery spring tab
→
the filter capacitor
→
the
power pin of the chip.
The filter capacitor for the chip's power pin should be placed as close as possible to the
corresponding pin of the chip.
