#
Analog Output (Output) - The full scale analog output level is specified in the Analog Characteris-
tics specification table.
Analog Power (Input) - Positive power supply for the analog section. Refer to the Recommended
Operating Conditions for appropriate voltages.
Serial Audio Interface Power (Input) - Determines the required signal level for the serial audio
interface. Refer to the Recommended Operating Conditions for appropriate voltages.
Test Output - These pins need to be floating and not connected to any trace or plane.
Mode Selection (Input) - Determines the operational mode of the device as detailed in
and 5.
Serial Control Port Clock (Input) - Serial clock for the serial control port. Requires an external
pull-up resistor to the logic interface voltage in I²C
gram.
Serial Control Port Data (Input/Output) - SDA is a data I/O line in I²C mode and is open drain,
requiring an external pull-up resistor to the logic interface voltage, as shown in the Typical Con-
nection Diagram; CDIN is the input data line for the control port interface in SPI
Address Bit 0 (I²C) / Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin in I²C
mode; CS is the chip select signal for SPI mode.
Test - These pins need to be tied to analog ground.
Direct Stream Digital Input (Input) - Input for Direct Stream Digital serial audio data.
DSD Serial Clock (Input) - Serial clock for the Direct Stream Digital serial audio interface.
