A 0.01 F capacitor must be attached from this pin to AGND if the Enhanced Stereo function
is used.
These pins provide the digital supply voltage for the AC-link section of the CS4294. These pins
may be tied to +5 V digital or to +3.3 V digital. The CS4294 and digital controller’s AC-link
should share a common digital supply.
These pins are the digital ground connection for the AC-link section of the CS4294. These pins
should be isolated from analog ground currents.
These pins provide the analog supply voltage for the analog and mixed signal sections of the
CS4294. These pins must be tied to +5 V analog supply. It is strongly recommended that +5 V
be generated from a voltage regulator to ensure proper supply currents and noise immunity
from the rest of the system.
These pins are the ground connection for the analog, mixed signal, and substrate sections of the
CS4294. These pins should be isolated from digital ground currents.
