! APPLICATION CIRCUIT

Note 9)

De-coupling capacitors must be connected between each power supply pin and GND pin.

regulator for THD.

Note 11) The bigger capacitor value of AC-coupling capacitors for headphone outputs realize better frequency

response characteristics, especially low frequency area.

Note 12) The above circuit shows only application example and does not guarantee the any electrical

characteristics. Therefore, please consider and check the circuit carefully to fit your application.
