Note 2.
The capacitance of an electrolytic capacitor decreases at a low temperature (0 ˚C or lower). Determine
the capacitance of the capacitor to be used taking this into consideration when the
µPD4714A is used at
a low temperature. Keep the wiring length between the capacitor and IC as short as possible.
