AD5311集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

AD5311屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的AD5311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(zhuǎn)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(zhuǎn)換為模擬視頻信號，再連接到屏幕驅(qū)動器，以顯示單色或彩色圖像。

GENERAL DESCRIPTION

The AD5301/AD5311/AD5321 are single 8-bit, 10-bit, and 12-bit buffered voltage-output DACs that operate from a single 2.5 V to 5.5 V supply, consuming 120 μA at 3 V. The on-chip output amplifier allows rail-to-rail output swing with a slew rate of 0.7 V/μs. It uses a 2-wire (I2C compatible) serial interface that operates at clock rates up to 400 kHz. Multiple devices can share the same bus.
