DAC7625UB集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

DAC7625UB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DAC7625UB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 DAC7624 and DAC7625 are 12-bit quad voltage

output digital-to-analog converters with guaranteed 12-

bit monotonic performance over the specified temperature

range. They accept 12-bit parallel input data, have

double-buffered DAC input logic (allowing simultaneous

update of all DACs), and provide a readback

mode of the internal input registers. An asynchronous

reset clears all registers to a mid-scale code of 800H

DAC7624) or to a zero-scale of 000H (DAC7625). The

DAC7624 and DAC7625 can operate from a single +5V

supply or from +5V and –5V supplies.

Low power and small size per DAC make the DAC7624

and DAC7625 ideal for automatic test equipment,

DAC-per-pin programmers, data acquisition systems,

and closed-loop servo-control. The DAC7624 and

DAC7625 are available in a 28-pin plastic doublewide

or a 28-lead SOIC package, and offer guaranteed

specifications over the –40°C to +85°C temperature

range.
