A digital/analog amplifier includes the following coupled in series: a pulse-width modulator, a control circuit, a power inverter and a filter. The power inverter comprises two transistors series-connected between a power supply terminal and a ground of the amplifier. The control circuit drives the transistors of the power inverter. One output of the filter forms an output of the amplifier to which a load is connected. The amplifier also comprises a capacitive circuit parallel-connected to the output of the power inverter.
