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.

VLS

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.

TST

Test - These pins need to be tied to analog ground.

Software Mode Definitions

SCL/CCLK

Serial Control Port Clock (Input) - Serial clock for the serial Control Port. Requires an external pull-up

resistor to the logic interface voltage in IC Mode as shown in the Typical Connection Diagram.

SDA/CDIN

Serial Control Data (Input/Output) - SDA is a data I/O line in IC 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 Mode.

AD0/CS

Address Bit 0 (IC) / Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin in IC Mode;

CS is the chip select signal for SPI format.

Stand-Alone Definitions

Mode Selection (Input) - Determines the operational mode of the device.

DSD Definitions

DSD_SCLK

DSD Serial Clock (Input) - Serial clock for the Direct Stream Digital audio interface.

DSD_EN

DSD-Enable (Input) - When held at logic ‘1’ the device will enter DSD Mode (Stand-Alone mode only).
