AK4368集成電路（IC）的數模轉換器（DAC）規(guī)格書PDF中文資料

AK4368屬于集成電路（IC）的數模轉換器（DAC）。由旭化成微電子株式會社制造生產的AK4368數模轉換器（DAC）數模轉換器（DAC、D/A、D2A 或 D 轉 A）可將數字信號轉換為緩沖或無緩沖的模擬電壓或電流。DAC 架構是否適合特定應用，要取決于分辨率和采樣頻率。DAC 通常用于音樂播放器，將數字數據流轉換為模擬音頻流。它們還用于電視和手機，將數字視頻數據轉換為模擬視頻信號，再連接到屏幕驅動器，以顯示單色或彩色圖像。

GENERAL DESCRIPTION

The AK4368 is 24-bit DAC with an integrated PLL and headphone amplifier. The PLL input frequency is synchronized to typical mobile phone clock frequencies. The AK4368 features an analog mixing circuit that allows easy interfacing in mobile phone and portable communication designs. The AK4368 includes a 3-D stereo enhancement circuit that operates with both the headphone amplifier and the stereo lineout. The integrated headphone amplifier features “pop-free” power-on/off, a mute control, and it delivers 50mW of power into 16?. The AK4368 is packaged in a 41-pin BGA package, deal for portable applications.
