Note 5. Analog signal inputted from LIN/RIN/MIN pin is gained to +6dB internally.
Note 6. DACL=DACR= “1”, MINL=MINR=LIN=RIN= “0”
Note 7. AC Load
Note 8. DACM= “1”, LINM=RINM= “0”
Note 9. HP-Amp no output. MCKO = “0”
Note 10. MINL=MINR=LIN=RIN= “0”. In power-down mode, all digital input pins including clock pins (MCKI, BICK
and LRCK) are held at DVDD or DGND. RSTN pin is held at DGND.
In case of MINL, MINR, LIN, RIN, LINM or RINM = “1”, the power supply current of AVDD pin is about 0.5mA
(typ.).
Note 11. PSR is applied to AVDD, PLLVCC, DVDD and HPVCC with 1kHz, 100mVpp.
