CS4294
FLT3D - Enhanced Stereo Filter
A 0.01 µF capacitor must be attached from this pin to AGND if the Enhanced Stereo function
is used.
8.4 Power Supplies
DVdd1, DVdd2 - Digital Supply Voltage
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.
DVss1, DVss2 - Digital Ground
These pins are the digital ground connection for the AC-link section of the CS4294. These pins
should be isolated from analog ground currents.
AVdd1, AVdd2, AVdd3, AVdd4 - Analog Supply Voltage
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.
AVss1, AVss2, AVss3, AVss4, AVss5 - Analog Ground
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.
