AD5371集成電路（IC）的數(shù)模轉換器（DAC）規(guī)格書PDF中文資料

AD5371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AD5371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 AD5371 contains 40 14-bit DACs in a single 80-lead LQFP or 100-ball CSP_BGA. The device provides buffered voltage outputs with a span of 4× the reference voltage. The gain and offset of each DAC can be independently trimmed to remove errors. For even greater flexibility, the device is divided into five groups of eight DACs. Three offset DACs allow the output range of the groups to be adjusted. Group 0 can be adjusted by Offset DAC 0, Group 1 can be adjusted by Offset DAC 1, and Group 2 to Group 4 can be adjusted by Offset DAC 2. The AD5371 offers guaranteed operation over a wide supply range, with VSSfrom ?16.5 V to ?4.5 V and VDDfrom 9 V to 16.5 V. The output amplifier headroom requirement is 1.4 V operating with a load current of 1 mA.
