Stresses beyond those listed under “absolute ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operation conditions” is

not implied. Exposure to absolute-maximum conditions for extended periods may affect device reliability.

(2)

AVDD is an internal 1.8-V supply derived from a regulator in the TAS3308 chip. Pin XTALI is the only TAS3308 input that is referenced

to this 1.8-V logic supply. The absolute maximum rating listed is for reference; only a crystal should be connected to XTALI.

(3)

DVDD is an internal 1.8-V supply derived from regulators in the TAS3308 chip. DVDD is routed to DVDD_BYPASS_CAP to provide

access to external filter capacitors, but should not be used to source power to external devices.

(4)

Pin XTALO is the only TAS3308 output that is derived from the internal 1.8-V logic supply AVDD. The absolute maximum rating listed is

for reference; only a crystal should be connected to XTALO. AVDD is also routed to AVDD_BYPASS_CAP to provide access to external

filter capacitors, but should not be used to source power to external devices.
