Test Circuit
Description of external parts
CIN
: Input coupling capacitor, for which 0.47
μF is recommended. Since the input pin potential is about 1/2 VCC,
the ceramic capacitor with small leak current is recommended.
CRF
: Ripple filter capacitor, for which 100
μF is recommended. Note that the capacitance below 100μF will cause
decrease in the ripple removal ratio.
CMute
: Capacitor for mute.
CVCC
: Power capacitor.
