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 Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
AVDD is an internal 1.8-V supply derived from a regulator in the TAS3218 chip. Pin XTALI is the only TAS3218 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 TAS3218 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 TAS3218 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.
