The invention relates to a class D power amplifier for digital audio input signals, e.g. according to the I2S standard. The inventive power amplifier comprises a PFC voltage supply and an A/D converter for returning the output signal of the amplifier and the voltage supply. The amplifier is controlled by means of digital regulation loops.
L'invention concerne un amplificateur de puissance de classe D, destiné à des signaux d'entrée audio numériques, par exemple des signaux conformes au standard I2S. L'amplificateur de puissance selon l'invention est composé d'une alimentation de tension à correction du facteur de puissance, et d'un convertisseur A/N destiné à retourner le signal de sortie et la tension d'alimentation. Ledit amplificateur est commandé au moyen de boucles de régulation numériques.
