| Abstract: | In this paper, a new kind of digital audio power amplifier on DDX is proposed and tested, which is UPA001 not only with a USB digital audio interface and but an analog audio interface. The introduction of DDX technology ensure the high efficiency and low distortion of UPA001, the introduction of digital audio interface and processing technology enable the audio signal transmission and processing without additional distortion and noise, and because of the introduction of technology of analog audio interface and processing, the equipment with output interface of analog audio can directly connect UPA001. |
