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 (DIN) and an output (103) for an output analogue audio signal (ΑOUT). The circuit also has a feedback path comprising an analogue-to-digital conversion module (202) for receiving an analogue feedback signal (VFB) derived from the output analogue audio signal and outputting a corresponding digital feedback signal (DFB). The analogue-to-digital conversion module (202) has an ADC (108), an analogue gain element (203) configured to apply analogue gain (GA) to the analogue feedback signal before the ADC and a digital gain element (204) for applying digital gain (GD) 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 (DIN).
