DAC7715U屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由美國(guó)德州儀器公司制造生產(chǎn)的DAC7715U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 DAC7715 is a quad, serial input, 12-bit, voltage

output Digital-to-Analog Converter (DAC) with

guaranteed 12-bit monotonic performance over the

–40°C to +85°C temperature range. An asynchronous

reset clears all registers to either mid-scale (800H) or

zero-scale (000H), selectable via the RESETSEL pin.

The individual DAC inputs are double buffered to

allow for simultaneous update of all DAC outputs.

The device can be powered from a single +15V supply

or from dual +15V and –15V supplies.

Low power and small size makes the DAC7715 ideal

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

data acquisition systems, and closed-loop servocontrol.

The device is available in a SO-16 package

and is guaranteed over the –40°C to +85°C temperature

range.
