Tap to voltage divider for internal mid-supply bias generator
If a 47-nF capacitor is attached, the TPA0162 generates an internal clock. An external clock can

I
Analog VDD input supply. This terminal must be isolated from PVDD to achieve highest performance.
Thermal Pad
Connect to ground. Must be soldered down in all applications to properly secure device on PC board.

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.
