10.2.2 Detailed Design Procedure

A rising-edge transition on SD input allows the device to start switching. It is recommended to ramp the PVCC voltage to its desired value before releasing SD for minimum audible artifacts.

The device is non-inverting the audio signal from input to output.

The GVDD pin is not recommended to be used as a voltage source for external circuitry.
