Master clock input pin. Used for input of 256-fs clock (duty: 40 to 60%).
Serial interface’s frame sync clock output pin.
Used for L channel data I/O when LRCLK = low level
Used for R channel data I/O when LRCLK = high level
Serial interface’s bit sync clock output pin.
Used for I/O of audio data from SI and SO in sync with BCLK. BCLK is
generated on-chip as MCLK divided by eight.
Serial interface’s data input pin. Used for serial input (synchronized with
BCLK) of audio data (two’s complement, MSB first).
No connection
Serial interface’s data output pin. Used for serial output (synchronized with
BCLK) of audio data (two’s complement, MSB first).
Digital power supply pin. Used for input voltage range of +3 to +5.5 V.
No connection
Digital ground pins.
Parallel data I/O pins. Used for input/output of address data and volume
setting data.
No connection
R-channel DAC output pin. When this pin is used, the R-channel DAC output
can be monitored without attenuation regardless of the volume setting.
R-channel analog audio output pin.
L-channel DAC output pin. When this pin is used, the L-channel DAC output
can be monitored without attenuation regardless of the volume setting.
L-channel analog audio output pin.
Analog ground pins.
Analog power supply pin. Used for input voltage range of +3 to +5.5 V.
No connection
