Working Principle

The NAU83P20YG amplifier works on pulse-width modulation (PWM). It allows the input voltage to be manipulated digitally, which enables efficient power transfer. This is accomplished by converting the analog input signal into a pulse-width modulated signal. The PWM signal is then amplified by the amplifier and sent to the output. The output voltage level is determined by the amplitude of the input signal, the carrier frequency of the PWM signal, and the switching speed of the amplifier. To maintain the desired output voltage and sound quality, it is important that the PWM signal is consistent and of high quality. This is achieved by ensuring a stable supply voltage, low output impedance, and relatively low harmonic distortion.
