AD5781集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

AD5781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AD5781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 AD5512A/AD5542A are single, 12-/16-bit, serial input, unbuffered voltage output digital-to-analog converters (DAC) that operate from a single 2.7 V to 5.5 V supply. The DAC output range extends from 0 V to VREFand is guaranteed monotonic, providing 1 LSB INL accuracy at 16 bits without adjustment over the full specified temperature range of ?40°C to +85°C (AD5542A) or ?40°C to +125°C (AD5512A). Offering unbuffered outputs, the AD5512A/AD5542A achieve

a 1 μs settling time with low offset errors ideal for high speed open loop control.
