Pin Description
4 Digital Power (Input) - Positive power supply for the digital section. Refer to the Rec-
ommended Operating Conditions for appropriate voltages.
5 Ground (Input) - Ground reference. Should be connected to analog ground.
31
6 Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.
Table 5 illustrates several standard audio sample rates and the required master clock
frequencies.
7 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.
8 Serial Data Input (Input) - Input for two’s complement serial audio data.
11
13
9 Serial Clock (Input) - Serial clocks for the serial audio interface.
14 Test - These pins need to be tied to analog ground.

19 Reset (Input) - The device enters a low power mode and all internal registers are
reset to their default settings when low.
32 Analog Power (Input) - Positive power supply for the analog section. Refer to the
Recommended Operating Conditions for appropriate voltages.
43 Serial Audio Interface Power (Input) - Determines the required signal level for the
serial audio interface. Refer to the Recommended Operating Conditions for appropri-
ate voltages.
18 Control Port Power (Input) - Determines the required signal level for the control port
and hardware mode configuration pins. Refer to the Recommended Operating Condi-
tions for appropriate voltages.
