AD8303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AD8303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。

GENERAL DESCRIPTION

The AD8303 is a complete (includes internal reference) dual,12-bit, voltage output digital-to-analog converter designed to operate from a single +3 volt supply. Built using a CBCMOSprocess, this monolithic DAC offers the user low cost and ease of-use in single-supply +3 volt systems. Operation is guaranteed over the supply voltage range of +2.7 V to +5.5 V making this device ideal for battery operated applications.The 2.0475 V full-scale voltage output is laser-trimmed to maintain accuracy over the operating temperature range of the device. The binary input data format provides an easy-to-use one-half millivolt-per-bit software programmability. The voltage outputs are capable of sourcing 3 mA.
