MUTE pin Function
When MUTE pin is “H”, output signals of LINEOUT and Headphone amplifiers are muted by force, and these signals are
output to common voltage.
Monaural output is muted to the input signal of analog volume (OPGA), but is not muted to the input signal of BEEP pin.
When MUTE pin is “L”, the AK4561 is normal operation.
When MUTE pin changes from “L” to “H”, pop noise does not occur from output signals of headphone and monaural
amplifiers, but the pop noise occurs from LINEOUT.
When MUTE pin changes from “H” to “L”, pop noise occurs from output signals of headphone, monaural and LINEOUT
amplifiers.
n
REC_MUTE Function
When REC_MUTE pin is “H”, output data of ADC become “L” by force after data of Lch or Rch is provided to all 16bit.
When REC_MUTE pin is “L”, the AK4561 becomes normal operation.
n
Analog Through Mode
This mode can be input to playback circuits after adding ALC output signal and shutter signal. This mode can be
controlled by PM4-3 bits.
