Abstract
According to an implementation, an audio switch circuit includes an audio switch configured to selectively couple an input node to an output node to transfer an audio signal across the audio switch. The audio switch has an on-resistance in response to the input node being coupled to the output node. The on-resistance of the audio switch changes by a first value in response to an input voltage of the audio signal increasing from a first level to a second level. The audio switch circuit includes an on-resistance compensation circuit configured to have an on-resistance that changes by a second value in response to the input voltage of the audio signal increasing from the first level to the second level. The on-resistance compensation circuit is coupled to the audio switch such that the second value at least partially offsets the first value.
