摘要
A die of an integrated circuit (IC) for implementing an audio amplifier comprises means (500) configured to generate at least one pulse-width-modulated signal (DS) in response to at least one first clock signal ( CLK2 ), and a first set of pads (502), wherein each pad of the first set of pads (502) is configured to provide a respective amplified pulse-width-modulated signal (ADS) to a respective external low-pass or band-pass filter (208). An amplifier stage (20) receives at input the at least one pulse-width-modulated signal (DS) and provide at output the amplified pulse-width-modulated signals (ADS). The die comprises further two power supply pads (300, 302), two pads (400, 402) configured to be connected to an external inductor (L), and a second set of pads (306, 308, 3100), wherein each pad of the second set of pads (306, 308, 310) is configured to provide a respective regulated voltage ( Vfloat, V1, V2 ). An electronic converter circuit (30) is configured to generate the regulated voltages ( Vfloat, V1, V2 ) in order to supply the amplifier stage (20).
