AD5332集成電路（IC）的數(shù)模轉換器（DAC）規(guī)格書PDF中文資料

AD5332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的AD5332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 AD5332/AD5333/AD5342/AD5343 are dual 8-, 10-, and 12-bit DACs. They operate from a 2.5 V to 5.5 V supply consuming just 230 μA at 3 V, and feature a power-down pin, PD that further reduces the current to 80 nA. These devices incorporate an on-chip output buffer that can drive the output to both supply rails, while the AD5333 and AD5342 allow a choice of buffered or unbuffered reference input.
