Mute Control 2 (Output) - Active-low mute output can drive external circuitry to eliminate the
clicks and pops associated with any single-rail output. This pin will become a high-impedance out-
put during power-down mode or when an invalid MCLK to LRCK ratio is detected.
Mute Control 3 (Output) - Active-low mute output can drive external circuitry to eliminate the
clicks and pops associated with any single-rail output. This pin will become a high-impedance out-
put during power-down mode or when an invalid MCLK to LRCK ratio is detected.
VCMBUF (Output) - Internally buffered VCMDAC
DAC Common-Mode Voltage (Output) - Filter connections for the DAC internal quiescent refer-
ence voltage.
Analog High Voltage Power (Input) - Positive power for the internal output buffer section.
Analog Ground (Input) - Ground reference for high-voltage section.
DAC Analog Audio Outputs (Output) - The full-scale output level is specified in the DAC Analog
Characteristics specification table.
Stereo Analog Inputs 1-5 (Input) - The full-scale input level is specified in the ADC Analog Char-
acteristics specification table.
Reset (Input) - The device enters a low-power mode when this pin is driven low.
ADC Overflow (Output) - Indicates an ADC overflow condition is present.
Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
Master Clock 2 (Input) - Optional asynchronous clock source for the DAC’s delta-sigma modula-
tors.
Serial Port 2 Left/Right Clock (Input/Output) - Determines which channel, Left or Right, is cur-
rently active on the serial audio input data line.
Serial Port 2 Serial Bit Clock (Input/Output) - Serial bit clock for serial audio interface 2.
Digital Power (Input) - Positive power for the internal digital section.
Digital Ground (Input) - Ground reference for the internal digital section.
Digital Interface Power (Input) - Determines the required signal level for the control and serial
port interfaces as shown in
Conditions” on page 13
Serial Audio Data Output (Output) - Output for two’s complement serial audio data.
Serial Port 1 Serial Bit Clock (Input/Output) - Serial bit clock for serial audio interface 1.
Serial Port 1 Left/Right Clock (Input/Output) - Determines which channel, Left or Right, is cur-
rently active on the serial audio output data line.
Master Clock 1 (Input) - Clock source for the ADC’s delta-sigma modulators. By default, this sig-
nal also clocks the DAC’s delta-sigma modulators.
for appropriate voltages.
