Differential Analog Output (Output) - The full-scale differential analog output level is specified in the
Analog Characteristics 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 inter-
face. Refer to the Recommended Operating Conditions for appropriate voltages.
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
Serial Control Data (Input/Output) - SDA is a data I/O line in I²C Mode and requires an external pull-
up resistor to the logic interface voltage, as shown in the Typical Connection Diagram. CDIN is the
input data line for the control port interface in SPI
Address Bit 0 (I²C) / Chip Select (SPI) (Input) - AD0 is a chip address pin in I²C Mode; CS is the chip
select signal for SPI format.
Test (Input) - These pins are not used in Software Mode and should not be left floating (connect to
ground).
Mode Selection (Input) - Determines the operational mode of the device as detailed in
Tables 4
DSD Serial Clock (Input) - Serial clock for the Direct Stream Digital audio interface.
Direct Stream Digital Input (Input) - Input for Direct Stream Digital serial audio data.
