AD5542CR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的AD5542CR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 AD5541/AD5542 are single, 16-bit, serial input, voltage output digital-to-analog converters (DACs) that operate from a single 2.7 V to 5.5 V supply. The DAC output range extends from 0 V to VREF.

The DAC output range extends from 0 V to VREF and 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. Offering unbuffered outputs, the AD5541/AD5542 achieve a 1 μs settling time with low power consumption and low offset errors. Providing a low noise performance of 11.8 nV/√Hz and low glitch, the AD5541/AD5542 is suitable for deployment across multiple end systems.

The AD5542 can be operated in bipolar mode, which generates a ±VREF output swing. The AD5542 also includes Kelvin sense connections for the reference and analog ground pins to reduce layout sensitivity.

The AD5541/AD5542 utilize a versatile 3-wire interface that is compatible with SPI, QSPI?, MICROWIRE? and DSP interface standards. The AD5541/AD5542 are available in 8-lead and 14-lead SOIC packages.
