AD9762ARU集成電路（IC）的數模轉換器（DAC）規(guī)格書PDF中文資料

AD9762ARU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AD9762ARU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。

PRODUCT DESCRIPTION

The AD9762 is the 12-bit resolution member of the TxDAC series of high performance, low power CMOS digital-to-analog converters (DACs). The TxDAC family which consists of pin compatible 8-, 10-, 12-, and 14-bit DACs is specifically optimized for the transmit signal path of communication systems. All of the devices share the same interface options, small outline package and pinout, thus providing an upward or downward component selection path based on performance, resolution and cost. The AD9762 offers exceptional ac and dc performance while supporting update rates up to 125 MSPS.

The AD9762’s flexible single-supply operating range of 2.7 V to 5.5 V and low power dissipation are well suited for portable and low power applications. Its power dissipation can be further reduced to a mere 45 mW without a significant degradation in performance by lowering the full-scale current output. Also, a power-down mode reduces the standby power dissipation to approximately 25 mW.
