Stereo Analog Input 4 / Microphone Input 1 & 2 (Input) - The full-scale level is specified in the ADC
Analog Characteristics specification table.
Stereo Analog Input 5 (Input) - The full-scale level is specified in the ADC Analog Characteristics
specification table.
Microphone Bias Supply (Output) - Low-noise bias supply for external microphone. Electrical charac-
teristics are specified in the DC Electrical Characteristics specification table.
Stereo Analog Input 6 (Input) - The full-scale level is specified in the ADC Analog Characteristics
specification table.
Auxiliary Analog Audio Output (Output) - Analog output from either the DAC, the PGA block, or high
impedance. See
Analog Power (Input) - Positive power for the internal analog section.
DAC Analog Audio Output (Output) - The full-scale output level is specified in the DAC Analog Char-
acteristics specification table.
Mute Control (Output) - This pin is active during power-up initialization, reset, muting, when master
clock to left/right clock frequency ratio is incorrect, or power-down.
Serial Audio Interface Power (Input) - Determines the required signal level for the serial audio inter-
face. Refer to the Recommended Operating Conditions for appropriate voltages.
Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
Serial Port 2 Serial Bit Clock (Input/Output) - Serial bit clock for serial audio interface 2.
Serial Port 2 Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently
active on the serial audio input data line.
