AD5328集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

AD5328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AD5328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(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，再連接到屏幕驅(qū)動器，以顯示單色或彩色圖像。

GENERAL DESCRIPTION

The AD5308/AD5318/AD5328 are octal 8-, 10-, and 12-bit buffered voltage output DACs in a 16-lead TSSOP. They operate from a single 2.5 V to 5.5 V supply, consuming 0.7 mA typical at 3 V. Their on-chip output amplifiers allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/μs. The AD5308/AD5318/AD5328 use a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards.
