DAC8871SBPW屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由美國德州儀器公司制造生產(chǎn)的DAC8871SBPW數(shù)模轉(zhuǎn)換器（DAC）數(shù)模轉(zhuǎn)換器（DAC、D/A、D2A 或 D 轉(zhuǎn) A）可將數(shù)字信號轉(zhuǎn)換為緩沖或無緩沖的模擬電壓或電流。DAC 架構(gòu)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(zhuǎn)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(zhuǎn)換為模擬視頻信號，再連接到屏幕驅(qū)動器，以顯示單色或彩色圖像。

DESCRIPTION

The DAC8871 is a 16-bit, single-channel, serial input,

voltage output digital-to-analog converter (DAC). The

output range is determined by the reference voltage, VREFH and VREFL. By properly selecting the reference,

the output can be unipolar or bipolar, and up to ±18V.

The DAC8871 provides excellent linearity (1LSB INL),

low noise, and fast settling (1ms to 1LSB of full scale

output) over the specified temperature range of

–40°C to +105°C. The output is unbuffered, which

reduces the power consumption and the error

introduced by the buffer. This device features a

standard high-speed clock (up to 50MHz), and a 3V or 5V SPI serial interface to communicate with the

DSP or microprocessors. For optimum performance,

a set of Kelvin connections to external reference are

provided.

The DAC8871 is available in a TSSOP-16 package.
