(5)音频处理电路(见图5)输入的图像、伴音中频信号经TDA9886处理后,由輰輥訛脚输出伴音信号到伴音功放电路。左、右声道的伴音信号经U107(TAA2008)的②、輮輧訛脚输入。TAA2008是一个数字功放集成电路(1C),采用数字功率处理(Digital Power Processing)技术,效率高且设计简洁,采用QFN封装。输入的伴音信号经TAA2008功率放大器后,由輳訛輥、輱訛輥脚输出左声道音频信号到左扬声器进行功率放大,由輰訛輥、⑩脚输出右声道音频信号
(5) audio processing circuit (see Figure 5) the input image, audio IF signal processing by the TDA9886, the error output by the 脚 roll sound accompaniment signal to the audio amplifier circuit. Left and right channel audio signal by U107 (TAA2008) ②, 輮 輧 Erroneous input. The TAA2008 is a digital power amplifier IC (1C) featuring digital power processing technology that is highly efficient and simple to design in a QFN package. The input audio signal by the TAA2008 power amplifier, the error feedback roller, the error feedback roller output left channel audio signal to the left speaker for power amplification, the error correction roller, ⑩ pin output right channel audio signal
