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 µPD4712C and 4712D
are used at a low temperature. Keep the wiring length between the capacitor and IC as short as possible.

Note 3. Because the standby pin is internally pulled down, if the standby pin is left open, operating mode is in
effect.
