(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 operating

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

(2)

Pin XTALO is the only TAS3108/TAS3108IA output that is derived from the internal 1.8-V logic supply. The absolute maximum rating

listed is for reference; only a crystal should be connected to XTALO.
