Note 6) De-coupling capacitors must be connected between each power supply pin and GND pin.

Note 7) The power supply for VDDO requires fast driving response performance such as a switching regulator

for T.H.D.

Note 8) The bigger capacitor value of external AC-coupling capacitors realize better low frequency response

characteristics. In addition, ESR(Equivalent Series Resistance) should be low.

Note 9) 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.
