8.5 Power Supplies

DVdd1, DVdd2 - Digital Supply Voltage

These pins provide the digital supply voltage for the AC-link section of the CS4298. These pins

may be tied to +5 V digital or to +3.3 V digital. The CS4298 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 CS4298. 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

CS4298. 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

CS4298. These pins should be isolated from digital ground currents.
