DAC7664集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

DAC7664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DAC7664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 DAC7664 is a 16-bit, quad voltage output

digital-to-analog converter (DAC) with 16-bit monotonic

performance over the specified temperature range. It

accepts 16-bit parallel input data, has double-buffered

DAC input logic (allowing simultaneous update of all

DACs), and provides a readback mode of the internal input

registers. Programmable asynchronous reset clears all

registers to a mid-scale code of 8000h or to a zero-scale

of 0000h. The DAC7664 can operate from a single +5V

supply or from +5V and ?5V supplies.

Low power and small size per DAC make the DAC7664

ideal for automatic test equipment, DAC-per-pin

programmers, data acquisition systems, and closed-loop

servo control. The DAC7664 is available in an LQFP-64

package and is specified for operation over the ?40°C to

+85°C temperature range.
