AD9106屬于集成電路（IC）的數(shù)模轉換器（DAC）。由亞德諾半導體技術有限公司制造生產(chǎn)的AD9106數(shù)模轉換器（DAC）數(shù)模轉換器（DAC、D/A、D2A 或 D 轉 A）可將數(shù)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(shù)字數(shù)據(jù)流轉換為模擬音頻流。它們還用于電視和手機，將數(shù)字視頻數(shù)據(jù)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 AD9106 TxDAC? and waveform generator is a high perform ance quad DAC integrating on-chip pattern memory for complex waveform generation with a direct digital synthesizer (DDS). The DDS is a 12-bit output, up to 180 MHz master clock sinewave generator with a 24-bit tuning word allowing 10.8 Hz/LSB frequency resolution. The DDS has a single frequency output for all four DACs and independent programmable phase shift outputs for each of the four DACs.
