Analog Audio Output (Output) - The full-scale output level is specified in the DAC Analog Characteris-
tics specification table
Analog Power (Input) - Positive power for the internal analog section.
Analog Ground (Input) - Ground reference for the internal analog section.
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.
Quiescent Voltage (Output) - Filter connection for internal quiescent voltage.
Not Internally Connected - This pin is not connected internal to the device and may be connected to
ground or left “floating”. No other external connection should be made to this pin.
Test Out (Output) - This pin is an output used for test purposes only and must be left “floating” (no con-
nection external to the pin).
Test Out (Output) - This pin is an output used for test purposes only and must be left “floating” (no con-
nection external to the pin).
Test Out (Output) - This pin is an output used for test purposes only and must be left “floating” (no con-
nection external to the pin).
Test Out (Output) - This pin is an output used for test purposes only and must be left “floating” (no con-
nection external to the pin).
Test Out (Output) - This pin is an output used for test purposes only and must be left “floating” (no con-
nection external to the pin).
Test Out (Output) - This pin is an output used for test purposes only and must be left “floating” (no con-
nection external to the pin).
Reset (Input) - The device enters a low power mode when this pin is driven low.
Digital Interface Power (Input) - Determines the required signal level for the serial audio interface and
host control port. Refer to the Recommended Operating Conditions for appropriate voltages.
Digital Power (Input) - Positive power for the internal digital section.
Digital Ground (Input) - Ground reference for the internal digital section.
Test Out (Output) - This pin is an output used for test purposes only and must be left “floating” (no con-
nection external to the pin).
Serial Port Master/Slave (Input/Output) - Hardware Mode Startup Option: Selects between Master and
Slave Mode for the serial port.
Master Clock (Input) - Clock source for the delta-sigma modulators.
Serial Clock (Input/Output) - Serial clock for the serial audio interface.
Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
