AD5791ARUZ集成電路（IC）的數模轉換器（DAC）規(guī)格書PDF中文資料

AD5791ARUZ屬于集成電路（IC）的數模轉換器（DAC）。由亞德諾半導體技術有限公司制造生產的AD5791ARUZ數模轉換器（DAC）數模轉換器（DAC、D/A、D2A 或 D 轉 A）可將數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，將數字數據流轉換為模擬音頻流。它們還用于電視和手機，將數字視頻數據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 AD57911 is a single 20-bit, unbuffered voltage-output DAC that operates from a bipolar supply of up to 33 V. The AD5791 accepts a positive reference input in the range 5 V to VDD ? 2.5 V and a negative reference input in the range VSS + 2.5 V to 0 V. The AD5791 offers a relative accuracy specification of ±1 LSB max, and operation is guaranteed monotonic with a ±1 LSB DNL maximum specification.

The part uses a versatile 3-wire serial interface that operates at clock rates up to 35 MHz and that is compatible with standard SPI, QSPI?, MICROWIRE?, and DSP interface standards. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V and in a known output impedance state and remains in this state until a valid write to the device takes place. The part provides an output clamp feature that places the output in a defined load state.
