Reset (Input) - Powers down device and resets all internal registers to their default settings.
Logic Power (Input) - Positive power for the digital input/output.
Serial Audio Data (Input) - Input for two’s complement serial audio data.
Serial Clock (Input/Output) - Serial clock for the serial audio interface.
Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the
serial audio data line.
Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.
Common Mode Voltage (Output) - Filter connection for internal quiescent voltage.
Mute Control (Output) - The Mute Control pin goes high during power-up initialization, reset, muting,
power-down or if the master clock to left/right clock frequency ratio is incorrect.
Differential Analog Output (Outputs) - The full scale differential analog output level is specified in the
Analog Characteristics specification table.
Ground (Input)
Analog Power (Input) - Positive power for the analog section.
Mode Selection (Input) - This pins should be tied to GND level during control port mode.
Serial Control Port Clock (Input) - Serial clock for the serial control port.
Serial Control Data (Input/Output) - SDA is a data I/O line in I
the control port interface in SPI mode.
