Note 1: Please see recommended operating conditions Note 1).
Note 2: Capacitor tolerance +/-5%
Note 3: Resistor tolerance +/-1%
Note 4: The QXpander effect (the spread effect) is adjusted with VR.
Note 5: We recommend using the regulator for the power supply which occurs the ripple.
Note 6: The mute signal which switches off the power supply of a power amplifier that is
connected with AA8334 appears in the 10 terminal.
Note 7: When the power supply is switched on, the pop noise occurs. We recommend
muting the pop noise by the power amplifier that is connected with AA8334.
