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.
NOTES:
1. AVDD is a 1.8-V supply derived from a regulator in the TAS3103 chip. Pin XTALI is the only TAS3103 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.
2. DVDD is a 1.8-V supply derived from regulators internal to the TAS3103 chip. DVDD is routed to pin 29 (DVDD_BYPASS_CAP)
to provide access to external filter capacitors, but should not be used to source power to external devices.
3. Pin XTALO is the only TAS3103 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 pin 6 (AVDD_BYPASS_CAP) to provide access
to external filter capacitors, but should not be used to source power to external devices.
