AD5343集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

AD5343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AD5343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 AD5330/AD5331/AD5340/AD53411 are single 8-/10-/12- bit DACs. They operate from a 2.5 V to 5.5 V supply consuming just 115 μA at 3 V and feature a power-down mode that further reduces the current to 80 nA. The devices incorporate an on-chip output buffer that can drive the output to both supply rails, but the AD5330, AD5340, and AD5341 allow a choice of buffered or unbuffered reference input.
