Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the
serialaudio data line. The frequency of the left/right clock must be at the audio sample rate, Fs.
Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.
Serial Bit Clock (Input/Output) - Serial bit clock for the serial audio interface.
Digital Power (Input) - Positive power for the digital section.
Digital Ground (Input) - Ground reference for the digital section.
Serial Audio Data Output (Output) - Output for two’s complement serial audio data. This pin must be
pulled up or down through a 47-k resistor to select Master or Slave Mode.
Serial Control Port Power (Input) - Positive power for the Serial Control Port.
Mode Selection (Input) - Determines the system sampling frequency range of the device.
Serial Audio Interface Select (Input) - Selects either the Left-Justified or
Interface.
MCLK Divide (Input) - Configures the device to divide MCLK by 1, 1.5, 2, or 4.
Reset (Input) - Input for resetting all internal registers to their default settings and for placing the device
in a low-power mode.
Analog Input (Input) - Analog inputs to the ADC.
Quiescent Voltage (Output) - Filter connection for the internal quiescent voltage
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.
Analog Power (Input) - Positive power for the analog section.
Analog Ground (Input) - Ground reference for the analog section.
Mute Control (Output) - Mute control signal used to control the state of the optional external analog mut-
ing circuitry. See
Analog Audio Output (Output) - Analog outputs for the DAC.
