Abstract:
A de-pop controller and method thereof are provided. The controller includes an amplifier and a comparator. The amplifier receives and amplifies an audio input signal, and then outputs an audio output signal. The comparator, coupled to the amplifier, receives a transient indication signal. The comparator compares the transient indication signal with a reference voltage, and the comparison result is then applied to control the driving ability of the amplifier for de-popping.
