DAC8830集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書(shū)PDF中文資料

DAC8830屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由德州儀器制造生產(chǎn)的DAC8830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(hào)轉(zhuǎn)換為緩沖或無(wú)緩沖的模擬電壓或電流。DAC 架構(gòu)是否適合特定應(yīng)用，要取決于分辨率和采樣頻率。DAC 通常用于音樂(lè)播放器，將數(shù)字?jǐn)?shù)據(jù)流轉(zhuǎn)換為模擬音頻流。它們還用于電視和手機(jī)，將數(shù)字視頻數(shù)據(jù)轉(zhuǎn)換為模擬視頻信號(hào)，再連接到屏幕驅(qū)動(dòng)器，以顯示單色或彩色圖像。

DESCRIPTION

The DAC8830 and DAC8831 are single, 16-bit,

serial-input, voltage-output digital-to-analog converters (DACs) operating from a single 3-V to 5-V

power supply. These converters provide excellent

linearity, low glitch, low noise, and fast settling over

the specified temperature range of –55°C to 125°C.

The output is unbuffered, which reduces the power

consumption and the error introduced by the buffer.

These parts feature a standard high-speed (clock up

to 50 MHz), 3-V or 5-V SPI serial interface to

communicate with the DSP or microprocessors.

The DAC8830 output is 0 V to VREF. However, the

DAC8831 provides bipolar mode output (±VREF)

when working with an external buffer. The DAC8830 and DAC8831 are both reset to zero-code after

power up.

For optimum performance, a set of Kelvin

connections to external reference and analog ground

input are provided on the DAC8831.

The DAC8830 is available in an SO-8 package and

the DAC8831 is available in an SO-14 package. Both

have industry standard pinouts (see Table 3, the

Cross Reference table in the Application Information

section for details).
