(1)

Stresses beyond those listed under absolute maximum 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 XTAL_IN 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

XTAL_IN.

(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 XTAL_OUT 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 XTAL_OUT. 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.
