Quiescent Voltage (Output) - Filter connection for internal quiescent voltage. VQ must be
capacitively coupled to analog ground, as shown in the Typical Connection Diagram. The nom-
inal voltage level is specified in the Analog Characteristics and Specifications section. VQ pre-
sents an appreciable source impedance and any current drawn from this pin will alter device
performance. However, VQ can be used to bias the analog circuitry assuming there is no AC
signal component and the DC current is less then the maximum specified in the Analog Char-
acteristics and Specifications section.
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling cir-
cuits. Requires the capacitive decoupling to analog ground as shown in the Typical Connection
Diagram.
Differential Analog Output (Output) - The full-scale differential analog output level is specified
in the Analog Characteristics specification table.
Mute Control (Output) - The Mute Control pins go high during power-up initialization, reset,
muting, power-down or if the master clock to left/right clock frequency ratio is incorrect. These
pins are intended to be used as a control for external mute circuits on the line outputs to pre-
vent the clicks and pops that can occur in any single supply system. Use of Mute Control is not
mandatory but recommended for designs requiring the absolute minimum in extraneous clicks
and pops.
Mode Selection (Input) - Determines the operational mode of the device as detailed in
and
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
Diagram.
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. GND if
unused.
DSD Serial Clock (Input) - Serial clock for the Direct Stream Digital serial audio interface.
