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 45):
An audio circuit as claimed in  claim 43  wherein said ADC, said analogue gain element and said digital gain element are located in a first ADC path and wherein the analogue-to-digital conversion module comprises at least one further ADC path configured to receive the analogue feedback signal, wherein each further ADC path comprises an ADC and is configured to apply different amounts of analogue gain and digital gain; and wherein the gain controller selects the ADC paths that contribute to the digital feedback signal.
