Pin Description
Digital Power
(Input)
-
Positive power supply for the digital section. Refer to the Rec-
ommended Operating Conditions for appropriate voltages.
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.
