Note 5) De-coupling capacitors must be connected between each power supply pin and GND.

Note 6) A switching regulator with a high response against a voltage fluctuation is ideal for the VDDO to obtain

better T.H.D. performance.

Note 7) Testing actual samples in your system is highly recommended. The typical application circuit is one of

examples.

Note 8) The transition time of MUTE and STBY signals must be less than 100us. Otherwise, a malfunction

might occur.

Note 9) (1)-(14) indicates pin number.
