AD5044屬于集成電路（IC）的數(shù)模轉換器（DAC）。由亞德諾半導體技術有限公司制造生產(chǎn)的AD5044數(shù)模轉換器（DAC）數(shù)模轉換器（DAC、D/A、D2A 或 D 轉 A）可將數(shù)字信號轉換為緩沖或無緩沖的模擬電壓或電流。DAC 架構是否適合特定應用，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)轉換為模擬視頻信號，再連接到屏幕驅動器，以顯示單色或彩色圖像。

GENERAL DESCRIPTION

The AD5024/AD5044/AD5064 are low power, quad 12-/14-/16-bit buffered voltage output nanoDAC? DACs that offer relative accuracy specifications of 1 LSB INL with individual reference pins and can operate from a single 4.5 V to 5.5 V supply. The AD5024/AD5044/AD5064 parts also offer a differential accuracy specification of ±1 LSB. The parts use a versatile 3-wire, low power Schmitt trigger serial interface that operates at clock rates up to 50 MHz and is compatible with standard SPI, QSPI?, MICROWIRE?, and DSP interface standards. A reference buffer is also provided on-chip. The AD5024/AD5044/AD5064 incorporate a power-on reset circuit that ensures the DAC output powers up to zero scale or midscale and remains there until a valid write takes place to the device. The AD5024/AD5044/AD5064 contain a power-down feature that reduces the current consumption of the device to typically 400 nA at 5 V and provides software selectable output loads while in power-down mode. Total unadjusted error for the parts is
