LTC2672集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

LTC2672屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的LTC2672數(shù)模轉(zhuǎn)換器（DAC）數(shù)模轉(zhuǎn)換器（DAC、D/A、D2A 或 D 轉(zhuǎn) A）可將數(shù)字信號(hào)轉(zhuǎn)換為緩沖或無緩沖的模擬電壓或電流。DAC 架構(gòu)是否適合特定應(yīng)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?jǐn)?shù)據(jù)流轉(zhuǎn)換為模擬音頻流。它們還用于電視和手機(jī)，將數(shù)字視頻數(shù)據(jù)轉(zhuǎn)換為模擬視頻信號(hào)，再連接到屏幕驅(qū)動(dòng)器，以顯示單色或彩色圖像。
