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 59):
An audio apparatus as claimed in  claim 57  further comprising a first connector for removably connecting to a mating second connector of a peripheral device wherein the apparatus is operable, in use, to supply the output analogue audio signal to the first connector for driving an audio transducer of a connected peripheral device.
