DAC7744E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DAC7744E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 DAC7744 is a 16-bit, quad voltage output digitalto-

analog converter with guaranteed 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 DAC7744 operates from

either a single +15V supply or from a +15V, –15V,

and +5V supply.

Low power and small size per DAC make the DAC7744

ideal for automatic test equipment, DAC-per-pin programmers,

data acquisition systems, and closed-loop

servo-control. The DAC7744 is available in a 48-

lead SSOP package, and offers guaranteed specifications

over the –40°C to +85°C temperature range.
