AD5541A集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

AD5541A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AD5541A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 AD5541A/AD5542A/AD5512A1 are single, 16-/16-/12-bit, serial input, unbuffered voltage output digital-to-analog converters (DACs) that operate from a single 2.7 V to 5.5 V supply.

The AD5541A/AD5542A/AD5512A utilize a versatile 3-wire interface that is compatible with a 50 MHz SPI, QSPI?, MICROWIRE?, and DSP interface standards.

These DACs provide 16-/12-bit performance without any adjust ments. The DAC output is unbuffered, which reduces power consumption and offset errors contributed to by an output buffer.

The AD5542A/AD5512A can be operated in bipolar mode, which generates a ±VREF output swing. The AD5542A/AD5512A also includes Kelvin sense connections for the reference and analog ground pins to reduce layout sensitivity.
