(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 XTAL_OUT is the only TAS3202 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 XTAL_OUT.

Note:

•

VR_ANA is derived from TAS3202 internal 1.8-V voltage regulator. This terminal must not be used to power external devices.

•

VR_DIG is derived from TAS3202 internal 1.8-V voltage regulator. This terminal must not be used to power external devices.

•

VR_PLL is derived from TAS3202 internal 1.8-V voltage regulator. This terminal must not be used to power external devices.
