Ground connection for circuitry. Connected to thermal pad
13, 24
LHPIN
6
I
Left channel headphone input, selected when SE/BTL is held high
LIN

I
Common right input for fully differential input. AC ground for single-ended inputs.
RLINEIN
23
I
Right channel line input, selected when SE/BTL is held low
ROUT+

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.
