DAC Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
DAC Serial Clock (Input/Output) - Serial clock for the DAC serial audio interface. Input fre-
quency must be 256xFs in the TDM digital interface format.
DAC Left/Right Clock (Input/Output) - Determines which channel, Left or Right, is currently
active on the DAC serial audio data line. Signals the start of a new TDM frame in the TDM digital
interface format.
Auxiliary Left/Right Clock (Output) - Determines which channel, Left or Right, is currently
active on the Auxiliary serial audio data line. Derived from the ADC serial port and equals Fs.
Auxiliary Serial Clock (Output) - Serial clock for the Auxiliary serial audio interface.
Auxiliary Serial Input (Input) - Provides an additional serial input for two’s complement serial
audio data. Used only in the TDM digital interface format.
Differential Analog Output (Output) - The full-scale analog output level is specified in the Ana-
log Characteristics table. Each leg of the differential outputs may also be used single-ended.
Mute Control (Output) - Used as a control for external mute circuits to prevent the clicks and
pops that can occur in any single supply system.
Quiescent Voltage (Output) - Filter connection for internal quiescent reference voltage.
Analog Power (Input) - Positive power supply for the analog section. See
acteristics” on page
Differential Analog Input (Input) - Signals are presented differentially or single-ended to the
Delta-Sigma modulators. The full-scale input level is specified in the Analog Characteristics
specification table.
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling cir-
cuits of the DAC.
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling cir-
cuits of the ADC.
Test In - This pin is an input used for test purposes only. It must be tied to ground for normal
operation.
Interrupt (Output) - Signals either an ADC overflow condition has occurred in one or more of the
ADC inputs, or a clocking error has occurred in the DAC/ADC as specified in the Interrupt regis-
ter.
Serial Control Port Clock (Input) - Serial clock for the control port interface.
Serial Control Data I/O (Input/Output) - Input/Output for I²C data. Output for SPI data.
