AD5542A集成電路（IC）的數模轉換器（DAC）規(guī)格書PDF中文資料

AD5542A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AD5542A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 AD5512A/AD5542A are single, 12-/16-bit, serial input, unbuffered voltage output digital-to-analog converters (DAC) that operate from a single 2.7 V to 5.5 V supply. The DAC output range extends from 0 V to VREFand is guaranteed monotonic, providing 1 LSB INL accuracy at 16 bits without adjustment over the full specified temperature range of ?40°C to +85°C (AD5542A) or ?40°C to +125°C (AD5512A). Offering unbuffered outputs, the AD5512A/AD5542A achieve

a 1 μs settling time with low offset errors ideal for high speed open loop control.
