Disposal of VBG and SG pin
VBG pin is standard voltage of built-in regulator and D/A converter. SG pin is the signal ground of built-in speaker
amplifier. Connect a capacitor between AGND pin so that a noise does not take these pins.
A capacity value recommends the following value. However, determine a capacity value after checking with the
system.
In addition, after each output voltage is stabilized, start playback operation.

The stable time of regulator output REGO pin voltage and AOUT pin
output voltage becomes long, so that connection capacity becomes
large.
The stable time of the speaker amplifier output SPM and SPP pin
voltage becomes long, so that connection capacity becomes large.
