Abstract:
This application relates to audio circuits, such as audio driving circuits, with improved audio performance. An audio arrangement ( 200 ) has an audio circuit ( 201 ) with a forward signal path between an input ( 102 ) for an input digital audio signal (D IN ) and an output ( 103 ) for an output analogue audio signal (A OUT ). The circuit also has a feedback path comprising an analogue-to-digital conversion module ( 202 ) for receiving an analogue feedback signal (V FB ) derived from the output analogue audio signal and outputting a corresponding digital feedback signal (D FB ). The analogue-to-digital conversion module ( 202 ) has an ADC ( 108 ), an analogue gain element ( 203 ) configured to apply analogue gain (G A ) to the analogue feedback signal before the ADC and a digital gain element ( 204 ) for applying digital gain (G D ) to a signal output from the ADC. A gain controller ( 205 ) controls the analogue gain and the digital gain applied based on the input digital audio signal (D IN ).

Claim (Index 55):
An audio circuit as claimed in  claim 52  wherein said analogue-to-digital conversion module of said feedback path is configured for receiving said analogue feedback signal derived from the output analogue audio signal at the output of the first forward signal path and also a second analogue feedback signal derived from the output analogue audio signal at the output of the second forward signal path and the audio circuit is configured to modulate the first forward signal path upstream of the branch node based on said digital feedback signal.
