PRODUCTION DATA
A rising-edge transition on RESET input allows the device to execute the startup sequence and starts switching.
A toggling OTW_CLIP signal is indicating that the output is approaching clipping. The signal can be used either to decrease audio volume or to control an intelligent power supply nominally operating at a low rail adjusting to a higher supply rail.
The device inverts the audio signal from input to output.
The AVDD pin is not recommended to be used as a voltage source for external circuitry when internal LDO is enabled (VDD ≥ 7 V).
