Design of Digital Audio Amplifier for Automotive Applications
Switching Power amplifiers are becoming quite common in audio applications, thanks to semiconductor technology advances, because of their intrinsic optimal efficiency. However usually they are used for low/medium quality application and low frequency loudspeaker systems. In this paper the design of a large bandwidth switching audio amplifier is presented. The amplifier is specifically aimed at automotive applications, where supply voltage, power consumption, and size are peculiar constraints. A prototype featuring reduced distortion, suitable for large bandwidth loudspeakers was realized and successfully tested.
