Note 19. Input from OPGL and OPGR pins. Analog Volume (OPGA=0dB) → Headphone Amplifier
Note 20. Input from OPGL and OPGR pins. Analog Volume (OPGA=0dB) → Monaural Amplifier
Note 21. Lch = -5.5dBV, Rch = no input or Rch = -5.5dBV, Lch = no input
Note 22. MPWR pin supplies 0mA.
Note 23. Then power supply current of MVDD is 0.2mA (typ.).
Note 24. In case of power-down, digital input pins of MCLK, BCLK, LRCK and SDTI are held “VD” or “DGND”.
Digital input pins of CCLK, REC_MUTE, CCLK, CS , CDTI and MUTE are held “VT” or “DGND”. PD pin
is held “DGND”.
