Pin Description
Digital Power
(Input)
-
Positive power supply for the digital section. Refer to the Recommended
Operating Conditions for appropriate voltages.
Ground
(Input) - Ground reference. Should be connected to analog ground.
Master Clock
(Input) - Clock source for the delta-sigma modulator and digital filters.
illus-
trates several standard audio sample rates and the required master clock frequencies.
Left Right Clock
(Input) - Determines which channel, Left or Right, is currently active on the
serial audio data line. The frequency of the left/right clock must be at the audio sample rate, Fs.
Serial Data Input
(Input) - Input for two’s complement serial audio data.
Serial Clock
(Input) - Serial clocks for the serial audio interface.
Test
- These pins need to be tied to analog ground.
Reset
(Input) - The device enters a low power mode and all internal registers are reset to their
default settings when low.
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
interface. Refer to the Recommended Operating Conditions for appropriate voltages.
Control Port Power
(Input)
-
Determines the required signal level for the control port and hard-
ware mode configuration pins. Refer to the Recommended Operating Conditions for appropriate
voltages.
Quiescent Voltage
(Output) - Filter connection for internal quiescent voltage.
